This elegant hotel is centrally located near San Francisco's Civic Center, walkable to the BART and local cultural landmarks such as the downtown library and, well, the opera! The rooms are snug but comfortable and well-appointed, and the on-site restaurant is excellent. I happened to stay during unusually hot weather (@ 90+ degrees)--during those 2 days a large box fan in the room helped as much as possible, but such days are few and far between. A bit of patience is required for the single elevator, but the operatic theme is carried throughout, the beds are comfortable, and the staff professional. I will definitely return. Highly recommended!
