I recommend this place for people looking for cheaper accommodations. Very much like a hotel - the rooms have everything you could need (although bathroom was down the hall), clean & they offer to change sheets/towels. Guests were all respectful of quiet hours.
Only stayed in SF for four days & found that the accommodation was well situated for traveling and made getting around much easier. Gets kind of rowdy outside at night, but nothing that bothered me or prevented me from sleeping.
