I'm very leary of Airbnb. We did a few searches for condos and were contacted by an "owner" through Airbnb. It was a crazy cheap price on some 6 bedroom villa in Terres Basses. My husband was skeptical and did some research. Someone had hacked into the site and was contacting email addresses that searched.
Hubby finally found the actual owner and let him know of the scam. I'm still getting the odd email, supposedly on Airbnb's behalf giving us deals. I would be very careful.
Having said that, I always get nervous when companies ask for a wire transfer. We take the hit of the credit card fee on VRBO or HomeAway just to be safe. Worth it for a bit of insurance in my opinion.
