My wife and I were vacationing to San Francisco and had a wonderful time at Stephen's place. The Castro is a vibrant community and centrally located in the city. We found most of our destinations to be walkable, and those that were not were a cheap uber/lyft ride away. Stephen is a very accommodating host and allowed us flexibility with check in/check out times.
The room was very comfortable and clean, and we felt that the neighborhood was very safe. Stephen had a lot of recommendations that helped us enjoy the city. We would definitely recommend to anyone looking for a nice stay in San Francisco.
P.S.- As others have noticed, there are multiple flights of stairs one must climb to reach the room. We did not find it at all a problem, but it is worth taking note for those that may have trouble with climbing a lot of stairs.
