I stayed two nights with a friend and the place is in a great place to explore San Francisco! Everything is within walking distante , Fisherman wharf, Coit Tower, Chinatown, Little Italy. We did not meet Irina but Greg Irina's roomate was very helpful. The room was clean and spacious, and Greg provided a key to lock the room. The bathroom was also clean but small and with a tiny shower.
If you are looking for a good location in SFO this is the place!
