I was in San Francisco May 31st thru June 5th and stayed at the Grand Hyatt starting June 1st. I was originally staying at the Hotel California/Savoy Hotel but the noise, room and amenties were much to be desired. So I called up the Grand Hyatt and they were having a special deal for the weekend and my stay (for 4 nights) cost roughly $900. When I entered the hotel I was treated like a VIP. They were extremely accomodating considering I was checking in at around 11:30 AM (check in is at 4 PM). The staff at the hotel were extremely kind and helpful. The room was beautiful, clean and the beds were extremely comfortable. The view from my room was beautiful and another plus about this hotel is that everything is within walking distance. Macys, Westfield Centre San Francisco (Bloomingdales, Sanrio, huge food courts, Bristol Farms, Nordstroms etc....), cable cars, Union Sqaure etc.....This hotel is wonderfully located and I highly recommend it to anyone going to San Francisco.
Pros: walking distance to all major San Francisco spots
Cons: Valet Parking is expensive but it is San Francisco
