I really enjoyed a 4-night stay at this JW recently and would stay there again. The area is the best feature. You can walk to pretty much everything of interest: Union Square, high end shopping, restaurants / pubs, nightclubs, etc. I like to jog along the bay when in San Fran and this hotel is 10-15 minute jog to the...

This JW Marriott is conveniently located one block from Union Square and is everything you would expect from a big city Marriott - very comfortable, helpful staff, etc. The Concierge room is open 24x7 and serves appetizers/snacks in the evening and breakfast in the morning. This hotel is 4 blocks from the Powell Street BART station and easily walkable unless... More

Business trip here for 3 bites. Good location and in walking distance of lots of shopping in Union Square along with access there to cable cars. Room was well appointed. Nice bathroom - comfortable bed. Fitness center has decent amount of machines as well as dumb bells weights. Concierge lounge on the 21st floor is one of the better ones... More

My wife and I stayed here for a couple of nights during the Holidays. I forgot to write a much deserved review. We had a very nicely appointed room with outstanding bedding. The Concierge Lounge was wonderful. The staff was friendly and efficient. The location was excellent for shopping, walks and sight seeing. Will stay here again on future trips!

While attending a conference at the Moscone I stayed here for 5 night. The hotel is very comfortable and well-appointed and reasonably convenient to the Moscone. I had breakfast in the Concierge Lounge and found it to be very good indeed. I stopped into the bar one evening but felt it just a bit empty and unappealing. The service in... More

After a five night stay, I think we have a good understanding about many of the key areas of this hotel. A little lengthy, but hopefully you'll gather a good picture of what went wrong. Check-in We used a massive amount of points. Normally, with points we are still treated as valued Platinum members and have never really noticed a... More

My wife and I were taking a trip to Maui, and we decided rather than taking the 9+ hour flight direct from Houston to Hawaii, which would include a puddle-jump from Honolulu to Maui anyway, we'd fly into San Francisco then fly from there direct to Maui. She grew up in her teenage years living in Mrin County (San Rafael)... More

Stayed for a conference 2 nights. First night was great. Second night the room next door was full of people having a party, slamming doors, screaming. Also, the bathtub was disgusting and clogged. I felt like I was in a dorm room back in college. Lots of drunk people in the elevators after 9pm. Will never stay here again.

This was the first time I had stayed at this hotel. The location was good, close to the financial district and close to lots of restaurants and bars. Also easy walking distance to the Bay and the Westfield Mall. The staff were all efficient and switched on and the room was clean, spacious and well appointed. Definitely a hotel to... More

We chose this hotel because of its location near Union Square and the fact that its a JW Marriott so expectations were high. The hotel did not disappoint. Great staff. A common area that stuns you visually - all the rooms face into a courtyard that is 17 stories tall. You enter the hotel through the first level where the... More
