I 'requested' my long weekend stay with a host I had previously spoken too, sadly they had forgotten to amend the times that their B&B would be available and the dates I chose were not up for grabs. Therefore, even if your request is denied Air B&B IMMEDIATELY take your money and 'HOLD' it for up to 7 days (I'm on day 6 and the money is not in my bank). They claim that they 'release' the money immediately when this happens and that it is up to the bank to get the funds back to you. Sorry, but I contacted my bank and no. It has nothing to do with the bank returning the money, it's because Air B&B TOOK money without even providing any service. So I am without the use of my £200+ now. Please be aware of this happening to you before booking and if possible contact the hosts privately before booking through the website. Certainly not worth the hassle. If you do not receive any service you should not have to pay a thing... or have your money 'on hold' for ANY length of time.
