I have had many great experiences with Airbnb, but unfortunately this was not one of them. The place itself was fine, but the host (Alan) was rude, invasive and uptight. The unit is under his apartment, and you can hear him pacing the floor and speaking loudly on the telephone starting early in the morning. The breezeway leading to the unit is described as private, but Alan feels no qualm about showing up there unexpectedly and knocking on your door without warning. He apparently does not know how to communicate via the app. I wanted very much to like this place, but I would recommend you find another place to stay in wonderful San Francisco.
