One of the most hospitable and well prepared places I've ever stayed, Mary went above and beyond in offering a great experience. It's very centrally located, with a short walk to Nob Hill, Chinatown, and downtown and a short bus ride away to most of the tourist spots. Not for the physically faint though, like others have noted, it's a steep climb up to the third floor and you really feel the "hill" part of Nob Hill. Patio is wonderful, bed was comfortable, although it got pretty toasty up on the third floor, but we were in SF for a heat wave.
