This reservation was made thru Instant Book at 10:30 on a Friday night for the next day. At 9am on Saturday David called and said he was sorry but the room was already booked. It sounded like he wasn't aware he was on Instant Book. He was very nice. Only, I was charged immediately and there didn't seem to be a way to refund me the full amount. David tried to give me a refund through the resolution center but it would only allow a $112 refund, which is what he was paid, not the whole $129 which I was charged. Ultimately, I had to go to my bank and file a claim against Airbnb for this amount. Very frustrating. Airbnb has gotten too big - I can no longer find a way to contact them directly with problems like this and I suspect David couldn't figure out how to either. In the future I will probably not use the Instant Book feature.
