I am trying to locate information on the Grand Hyatt San Francisco Hotel on Union Square. The address is 345 Stockton. What can you tell me?

Bar at the top (37th floor, I think)Jazz usually nightly.
Recently renovated
Check the Hyatt website for more info

Great location, very nice, some rooms on small side but well appointed, However, too expensive for my budget,

Excellent restaurant on top floor with a great view.

My husband and I stayed there for five days last year. It's a great location. The hotel is fine. You'll find that it's not one of the nicer Hyatts, but you're paying for location. The concierge was exceelent and got us booked into some high demand restaurants on short notice. It's a quick walk to Chinatown, and there's a trolley line right behind the hotel. They had great room service!
