My husband and I stayed 5 nights in early June. We had a room on the 8th floor on the courtyard side of the building. It was extremely quiet! We didn't hear any city noise. The room is on the small side, but that is to be expected in the city. The room was very clean and had modern decor. The bed was comfy too!
The staff were very friendly and always greeted us when we came and went. We also had dinner and drinks at Gaspar, the new restaurant in the hotel. The food and drinks were excellent.
The location is very convenient to Union Square and Chinatown and public transportation was close, although we walked a lot of places because that's how we roll. I would avoid walking through the Tenderloin though.
We had a great experience at Galleria Park and will definitely stay here again when in SF!
