Great, historic hotel at the top of Nob Hill. Rooms are older and could use an updating, but the bed was very comfortable and it was very quiet. The location is great, but you're going to have to walk up and down the hill to get anywhere. Worth staying here if for no other reason than going up to the Top of the Mark and get you a drink. (You don't need to stay there for that). Otherwise, the hotel seemed a bit understaffed, but the stop was accommodating.
As a Diamond Ambassador, I expect to get everything that I'm owed without asking, and I did. To me, this is huge. Too bad IHG doesn't have more upscale hotels in the US.
