We stayed at this apartment during our 4 day stay in San Francisco and couldn't have made a better choice. The apartment is easily reachable with public transport from the airport and is very centrally located. We basically walked everywhere, although it is quite a trip sometimes. There are a lot of homeless people in the area (as the description clearly states), but this is really not a problem. There are a huge amount of bars and restaurants in the area, we tried some of Rye & Robin's recommendations and had a great experience each time
I would definitely recommend this apartment to anyone looking for a good place to stay in San Francisco.
