Don't go there. In June, I booked a flat in Williamsburg, Brooklyn for the dates of August 15 to 17. At the time of booking, I went through the full online registration process and then pre paid for the stay by credit card, also providing my address and phone number. Over the next 60 days or so, I received several emails from both AirBnb and the host, reminding me of my reservation and asking for my arrival time. I thought AirBnb was switched on.
Then, less than 24 hours prior to my scheduled 4:00 PM check in time on August 15, I got an email from the "Trust and Security" division at Air, requiring me to send them a copy of my photo ID via email. Failing this option, my reservation would be cancelled. Obviously, I wouldn't email a copy of my passport to the Pope. I suggested to Air that I present my passport on arrival. No go. I was forced to make a last minute, very pricy booking at a Brooklyn hotel.
AirBnb created a needless last minute travel hassle. They also cost me $500.00. Never again.
