I recently stayed at the JW Marriott Union Square while attending a conference at the Moscone Center. The hotel is located in a great central location that allows you to venture out a few different directions. The hotel itself is very clean and the room was quiet. The hotel staff is very friendly and the hotel amenities are above average. I did have two issues with this hotel but both are minor and not deal breakers. Half of the elevators were not in service and therefore it was an extremely lon... Read more

My husband and I recently stayed at the JW Marriott for our 35th wedding Anniversary. Great service, nice room and the best part was that we were in the heart of the city. We love seeing a city by walking and so it was central to many of the places we wanted to see. About a two mile walk to the pier and the Concierge was very helpful in getting us tickets for Alcatraz and the hop on hop off bus. We did not plan that ahead of time and it was great being able to do the ferry to the Alcatraz island... Read more

We stayed for two nights over a weekend as a part of a long road trip. The staff was very professional and accommodating for what we needed. They did charge us for an oversized vehicle in valet parking even though we drive a sedan that had a roof top box on it - what would they do for a truck? (Also, if you are driving here, be aware that you can't access the driveway from the front of the building, you need to approach from the back along the side street to turn in.) Concierge was great, sugges... Read more

The hotel was nice. I would definitely stay here again! Service was excellent! It is in a great location in union square too! Rooms were adequate size and it's easy to walk to the mall, coffee shops, tea houses, and restaurants. It's a great place to stay.

We had a king bedroom. It was small (about 300 square feet). The hotel is very modern and clean. Great location. Be aware that valet parking is $65 per night, which is about average for S.F. I would definitely stay at the hotel again.

We were in this hotel for three nights and we're pleased with the size of the room. We would have preferred a suite but none were available. Our room with two queen beds also had a good size desk, a refrigerator, a shower and a separate tub. The hotel manager was very accommodating and exchanged the regular chair for a more comfortable. When I mentioned that my husband was ill, she offered to have some nourishment sent up to him. A large fruit bowl, delicious breakfast bars and two very tasty... Read more

I was very pleased with our stay at JW Marriott. The hotel was clean and the room was large. From what I can tell, all the rooms are facing a street so you will have street noise. We asked to change rooms originally because of how loud the street noise was and were quickly accommodated and given a room on a higher floor. I really don't have any negative comments for this hotel. We took advantage of the concierge and they were super friendly and willing to help. I would recommend this hotel for a... Read more

This hotel is fine, but definitely not swank. I stay at the JW Marriott in Miami frequently, and I was expecting a lot more based on that--this was like a run of the mill Marriott. Everything was clean but kind of dated looking, and my room had a support pillar in a totally weird spot in the middle of the room. There's no place to just grab coffee in the atrium--you have to get the restaurant staff to make you a to-go cup. Also, the the concierge was unbelievably unhelpful--my friend and I w... Read more

You can not go wrong with the JW. The front desk staff is wonderful. Welcome drink (non-alcoholic) was provided and they upgraded me to a larger room due to my Platinum status. The room does not have the most modern design, but it's clean and spacious. The bathroom has great shelve space and lots of room around the sink (pictures attached). However, the shower room is REALLY TINY (you go inside and that's all the space you have. Can't even stretch your arms to the side), and the tub has no... Read more

The hotel met high expectations. The room was small, but the layout and features were very functional. Outstanding location as well. The front desk was professional. The hotel clearly belongs in an upper-end market and delivers what travelers want.

Spent four nights when we toured San Francisco. Warmly and promptly greeted and in the room in minutes. Clean and comfortable with excellent bedding as well as a large bath. Right next to Chinatown and quickly traverse the city by public transportation. Everyone with whom we interacted from the desk staff to the breakfast "crew" was joyful and added to our wonderful visit. This great hotel stay just added to our positive memories of San Francisco.

This hotel seems dated - A lot of the amenities in the room (sheets, towels, etc) seemed to be of lower quality than what you would typically expect in a JW. Shower was very small and rather awkward to use. We will probably stay elsewhere in San Francisco next time. Disappointing, as JW's typically offer excellent facilities.This was a reward stay, and I think that less points should have been required for the stay due to the average quality. We also had a drink in the bar in the lobby. The wro... Read more

Typical JW Marriott business style venue - comfortable and well-appointed. Location is good for anything in Union Square or financial district. Easy walk to Powell Street Station for Cable Car or for BART. Check in process was off. Rooms we requested were not available and it seemed difficult to manage.

I was in for the San Francisco Marathon. I booked two for me and a shared room for my mother and sister. Because I am a gold member there was supposed to be b-fast and late night snacks with drinks in the concierge lounge. We were told it would not be available until Sunday night, which was the last night of our stay. This was unfortunate because I was counting on this benefit. They said they were issuing 2,000 points to my rewards. I looked at them as if they were crazy....2,00... Read more

We stayed for four nights in July 2016. Comfortable room. Bathroom was big and included a full tub separate from the shower. That being said the shower was small. Almost impossible to shave my legs. And I didn't want to have to shower then use the he tub to shave, so a bit of a downer there. But the bigger problem was the outside noise. Our room faced Post, eleventh floor. Every horn beep, anyone yelling, brakes on big trucks was heard up in the room. We didn't eat in the restaurant bec... Read more

We loved the location of the JW Marriott near Union Square. Walkable to many sites (Ferry Building) and the hotel rooms are very nice. The service at this hotel is also very good - very attentive with quick response to any requests. We would definitely stay here again.

I was there for business and had appointments around the bay area. Easy to get just about every where. Just off the square a bite. Plenty of great eating spots, great for morning walks. Higher floors has great views of the city and the bay. Not for the budget minded, but good value. Enjoy the city and the hotel.

We thoroughly enjoyed our stay at the JW Marriott. Staff were extra helpful and friendly and the room was spacious, clean and well appointed. Would recommend for an alternative to the mega-hotels on Union Square.

When I walked into this hotel I thought it was a re-purposed Embassy Suites: big atrium with elevators up the center, dated decor in lobby and rooms; etc. It doesn't befit a JW Marriott branding. But it sounds like it's going through a refurbishment next year, which it really needs. Rooms are big enough and with a lot of light. However even 18 floors up, it's noisy from the street below. And the bathrooms are incredibly outdated: fixtures, colors, everything needs a refresh. Aromatherapy ... Read more

Paid significant amount for 2 nights (including breakfast) and shockingly, the experience was never even close to good. Your frustration starts from being asked many times during your breakfast that "did you pay for your breakfast?" (not to mention they finally charged us for one breakfast!!?? only because we've booked through BTW, most obvious requirements for rooms are missing unless you ask for because they think that's upon request!!! believe me every even basic requirement.

Poorly appointed and in dire need of a refresh. I stayed here for 6 days for a convention and could not wait to leave it. The worst part was the windows in the rooms - single glazed, and from the last century- meaning the noise level from the streets 8 floors below was unbearable, even with good ear plugs in. Crazies screaming at 2am, then delivery trucks at 0600 onwards... room smelled slightly of damp too. Not worth $300+ per night, no breakfast.

I have stayed here in the past and used to be very fond of this property. I stopped in yesterday late morning and asked when I could get a room. The gentleman at the desk took my cell phone number and after 4 hours, near 3 in the afternoon I called and asked a lady at the desk if my room was ready? She got my name wrong about three times and finally a miracle happened she found a room. The property has hit the point where they need a remodel. My room has broken components on the desk...

Compared to "lesser" hotels in the area for the same price the JW was a great value at $500+. Very clean hotel and fancy amenities you can expect from the brand. It didn't appear much was going on in terms of dinner or lunch, but the breakfast at level 3 was excellent.

First of all this is a beautiful, wonderful hotel full of art of all types. I spent hours just wandering thru the hotel looking at the unique art works. The staff on check-in was friendly and helpful (they had sangria and cookies!). Our room wasn't ready because they had to make it feather-free. We waited until they called us (about 3 hours) and went to our room. Weirdly, our room was still full of feathers. We called down and they were confused but said they would fix it. It took about a...

First off, the inside of this hotel is really neat. The outside doesn't do it justice when you first arrive. I highly recommend having a drink and sitting in the lobby for a few minutes. The lobby has beautiful decor and the bar staff is incredibly friendly and willing to answer any questions you have! Food and drinks at the hotel are expensive but the service is worth the cost. Check in was very quick and easy & the standard rooms are perfect - including very LARGE bathrooms. I appreciated ha... Read more
