This isn't always the case. I was heading to Milwaukee for a wedding a few months back and booked an AirBnB a while in advance. My host bailed three days before we arrived and the PGA Championships were in town. There wasn't a single vacancy and AirBnB customer services was completely unresponsive. I had to send multiple emails before they bothered to respond and then they offered a $40 credit toward another booking. That policy is probably fine in NY or another city with adequate inventory but Milwaukee had no downtown options left at any price. I can understand that AirBnB has no control of a host but their complete lack of customer service response was pathetic. I have no plans to ever use them again.
