I have stayed at the Four Seasons, San Francisco on many occasions. My most recent stay was last week. It never fails to deliver. Service is superb, staff attentive and polite and they take care of any little requests you make without fuss. Rooms are very comfortable and the free use of the LA Fitness health club with all its gym and pool facilities on the FS premises is an added bonus. If you are awake in the wrong timezones and in desperate need of caffeine early in the morning, a nice touch is the fresh mini-muffins with great coffee. Great attraction is its proximity to the shopping area and access to tourist attractions.
