Great hotel
Very spacious room. Centrally located 2 blocks away from Union Square. We were not bothered by any noice, not like other hotels where you hear a lot of noise from conversations in the next door room. Very clean room and spacious considering it is SF. I will definitely stay on this hotel again.

Anniversary stay at the JW Marriott in SF
The hotel is in the center of everything - shops, restaurants, and more!

Good 6.0
A standard 4-star hotel experience
Pros: The hotel is conveniently located in downtown SF in Union Square. It is walkable to many places, which I really liked. The room itself was clean and decent. We ordered room service for one night, and the food was nicely seasoned and well-prepared. Cons: I found the entranceway to the room quite narrow, awkward, and inconvenient--there is a huge pillar we would need to pass through before entering the room. As soon as we walked into the room, we noticed that there was a very high-frequency noise coming from the ventilation. We called the front desk and they were able to send someone to fix it for us right away, which I should give them credit for. We were told that the ventilation in the bathroom automatically turned off at 11 pm every night due to multiple complaints about the noise, which was unheard of to me. This made "doing business" in the bathroom after 11 pm an uncomfortable experience for me and my family.
