Our large, top-floor flat is walking distance from Golden Gate Park and the Presidio, with speedy access to downtown. In addition to a large bedroom, there's a huge living room, an eat-in kitchen, and a balcony and yard. Within 3 minutes (walking!) of some of San Fran's best restaurants.
Within 2 blocks are several different MUNI lines (the 1, the 38, the 33, and the 44) which can take you almost anywhere in the city. But even on foot, there's much to see, including Clement Street, Presidio Heights, University of San Francisco, and both Golden Gate Park and the Presidio.
