I can't recommend this rental highly enough. On a quiet side street in the middle of a fun, happening neighborhood, the apartment is efficient, extremely comfortable, spotlessly clean, and looks like a page out of Dwell. Mario is a courteous, responsible host and we felt immediately at home here. One con: street parking is brutal (but there's a garage a block away).
Pros: everything else, including proximity to great shopping and restaurants. Even the Sunday street fair on Hayes was relaxed and cool. I can't imagine a more pleasant week in San Francisco.
