I stayed for 3 nights in one of premier rooms which are fairly large for San Francisco. It was expensive but the neighborhood is vibrant with tons of things to do in the mission area. Took advantage of the large and beautiful swimming pool. Had drinks in the wonderful bar on the main floor which was romantic. I requested and got the house Bentley to bring us to a nearby restaurant which was quite a treat. Staff were all wonderful. Definitely better than Four Seasons San Francisco due to the newer facilities and better location. Would be a wonderful place to live ( at the residence at St.Regis) if we live in San Francisco.
