Nice homey 2-bedroom place on a quiet side street in the Mission District, two blocks from a BART station and maybe five blocks from the Church streetcar line. Lots of nice touches -- tons of linen, fully stocked kitchen pantry, washer and dryer -- and bookish living room.
The proximity of a BART station means that reaching SFO and downtown is extremely fast and simple, even at rush hour. The house is also an easy walk from a major confluence of Muni streetcar and bus lines on Market Street, so we were able to zoom around town on public transit (including Fisherman's Wharf, which is a direct shot on the F streetcar). Much more efficient than driving a car.
Nice selection of moderately prices restaurants nearby, too, and Doris left a few hand-written suggestions on the kitchen table.
The Mission neighborhood is a little rough around the edges for children, but for adults this is a great alternative to a pricey tourist hotel.
