This was my first airbnb and I must say that Jason is perfect host. When I arrived Jason gave me a tour around the place, showed me where everything is, I was a bit surprised by the fact I could use/eat/drink stuff from the fridge (there was even icecream). :)
He has a lot of material about SF prepared for you if you need it. One night I even got myself locked out of the room and he helped me get back in. :)
Room was in real life as it is on the pictures, everything was clean and great.
One thing I did not like is neighbourhood because of homeless people around, but that is standard in most of SF.
