Sadly, AirBnB has failed for me more than 90% of the time. In NYC there were overtly shady people, such as a dude who had at least 3 accounts, 2 of which he would pose as women. However, the biggest problems are flakes and people who list their apartment as being available when it really isn't. To AirBnB's credit, housing in NYC is shady to begin with, and the one time it worked, it was great.
