Great stay!
After reading many of the reviews, I decided to stay here for 4 nights with my wife. We stayed in a deluxe king room on the 11th floor. Nice views, no street noise, AC worked, TV was great, etc.
I saw that some people complained about the AC not working or the water pressure being low, but I don't believe this to be the case. In addition, I believe the price to be reasonable (~$220/night). The location is excellent (top of nob hill), and is a hearty uphill walk from Union Square.
My room was cleaned every day, and the bathroom had nice tile work to it.
Definitely get a drink in the afternoon or breakfast on top of the mark! Certainly worth it for the views.
Would I stay here again? Yes.
