First time staying at this hotel and it will not be the last. We were in a junior suite which included a king bed (very comfortable) and a sitting area, and a large updated bathroom. On the advise of other reviewers, we asked for an upper floor - definitely quiet - no street noise. The staff was friendly, professional and... More

Very nice hotel. The staff is terrific. We were here for the most recent NADA Convention and really enjoyed this particular hotel. The room was very spacious and the bed was incredibly comfortable. Very nicely appointed and extremely quite for a downtown hotel. Union Square is just a block away as are the cable cars. Moscone Center is within a... More

Wow is all that comes to mind. Neeraj Miglani and the team at the JW Marriott San Francisco Union Square. A team of us have been working in San Francisco for a number of weeks. Most of the team are loyal Marriott customers. Our reservations were all set and everyone on our team received the negotiated rate for our employer... More

quite decent, if a little dated hotel. Not really on Union Square, but a block or so away. Smallish lobby. My room a bit oddly shaped and the shower far from commodious, but it worked fine. Small sink with little room around it. Bed quite comfy, all in order Not a standout, but a better price than many on a... More

Standard Marriott, tiny bathroom but room was clean and relatively quiet since we were located near the back of the building. We wanted a location within walking distance of BART and other transportation. The hotel gave us a handout advising guest to reserve cabs through the doormen hours in advance due to an alleged shortage. So we called the cab... More

In SF for business, stayed right next to union square. You know how noisy downtown can be... but not at the Marriott. Just ask for a high floor and escape the noise. Will be back. Room rates good for the quality of property and status room. Thank you!

As a Marriott Elite member, we stayed at this hotel for two nights using points. Upon check-in we were upgraded to a junior suite. It was a beautiful corner room on the 12th floor. Large bathroom, nice big windows and a switch to push if you'd like a personal valet! Room was very clean and my only complaint was that... More

This was my first stay at a JW Marriott although my husband is a silver elite member and has stayed at the JW's around the world. I must say it was a very disappointing experience. The hotel itself is very pretty and the location is wonderful. I gave it an average rating because I considered my check-in experience pleasant. My... More

I was very happy during this stay. I am a Marriott rewards member so when i got there to check in they upgraded my room. They put me in the ocean view suite, which was gorgeous, I was on a trip with my girlfriend, fiance now, and this was our last stop from a 10 day national parks tour, and... More

While everything in this hotel is well done, the value for money is horrible! I was initially booked at the San Francisco Marriott on Union Square but when I found out that one night would cost more than $400 (imagine that!), I quickly went online to see if there were any other Marriott properties in San Francisco more reasonably priced....
