Someone should keep a check on this service. For ex: Allow only single home owners to rent, else this is going to be a huge problem.
The rental that I took was owned by a real estate agency even though the profile showed the foto of a family. I didn't realize that until I thought I will meet with the sweet family, so I called the phone number and it was picked up by receptionist and said there is no family !
So I asked AirBnB about this rental portrayed as a family owned rental, but was really a real estate agency, their reply was "Its legal" and I should have read the fine print before renting.
