Great place, super convenient for the Castro and exploring San Francisco. Ideally located two blocks from the J line and classic F line trams about 10-15 mins in to Union Square area.
Stephen is a courteous and professional host - he was available but just left us alone to do our own thing as we wanted.
The room is a decent size with a good bathroom 1 metre away and there is a seating area and kitchen available next to the room. We would definitely stay here again when in SF.
