Susan's flat is an absolutely wonderful place to stay. It's roomy, well-equipped and full of character and Susan herself is an absolute delight. A really good source of local information and a very warm host. The location is second to none - right next to the Castro, the Mission and Haight street, at the quiet end of a cul-de-sac next to a rather pretty park, which has the tram to downtown and the beach on the other side (literally a minute's walk away). Very highly recommended!
