Disappointing for a Grand Hyatt
We stayed in June of this year, first time in San Francisco. Debated over the Fishermans Wharf area or downtown. Opted for downtown and the Grand Hyatt as I'm a Hyatt Platinum card holder. 
Room was ok, not particularly large, but it was just a standard room. 
Maybe this is the norm for San Fran, but I just though small and the whole hotel just lacked any atmosphere and life.
