I would say Herbert's place was very affordable for San Fran and in a decent location. It was about a 30 min drive to the main sites. The downside to this air bnb was definitely the air mattress & the fact that that the room has no lock. It was quite cold in the room (it's in the basement) but a space heater was provided so that was fine. We never met Herbert but that didn't bother us. Overall we had a good stay.
