I have been renting from airBNB quite a lot particularity on my trips to Lyon in France.
I have to say that airBNB doesn't seem to be a trustworthy organization. Their client service is nonexistent. NO mail or direct phone to contact them.
Every time they charge non authorized amounts in my credit card and I have to claim to no avail. Last time I had to request anti fraud services of amex. I do recommend you people to be very careful with this company in order to prevent fraud and rip-off. On top of that strange way of operating their fees are outrageous. A rip-off no doubt.
They don't have a mail for us to complaint but their address is:
