It was a Dispatches programme I think, about 5 or 6 years ago maybe a bit longer about the problems at the time in Barcelona. It specifically mentioned tax dodging, I decided then that I wouldn't use them. More recently a group of my friends had booked a large apartment in Scotland through Air bnb, just before they were due to go it was cancelled as the owners had received a better offer from some other people almost double the previously agreed amount. They are looking at ways to try and get some compensation.
