Tried to book a room in San Francisco. Reservation was never processed by Airbnb, however my $1000 payment was ABSOLUTELY processed.
It was VERY difficult to reach a human being to try to resolve the problem. When I did--finally--they were no help whatsoever (even spoke to a supervisor--no joy).
In short, I DO NOT recommend you do business with Airbnb. If your experience is anything like mine, you will absolutely regret it if you do.
