The Park Hyatt San Francisco is an excellent Hyatt property. The hotel is in the downtown area, near the financial district (and only a few blocks away from one or two other Hyatts). The hotel has extensive amenities, including a nice restaurant and lounge. (We spent time in the lounge, but not the restaurant.)

For our room, we were upgraded to a "deluxe" room. Basically, this is a hotel room with a larger bathroom and a sitting room (not a full suite). We had a large balcony with room enough for 4 people to sit outside. We had a partial bay view, but mostly our view was of other buildings. Still, a very, very nice room.

Although hyatt.com wanted $250+ for rooms at this property, we were able to find a better rate at Expedia (an Internet weekend special). I would definitely return to this hotel again.
