Have had 2 bookings cancelled by hosts recently. Booked in May for New Year in Lanzarote, 2 weeks later they cancelled as they had double booked. Found a new villa, booked 2nd June, cancelled 6 weeks later with no explanation. Shouldn't be allowed to happen. Air BnB say its rare for hosts to cancel, well not in our case. We have spent £3000 on flights and have to start our search all over again....not on Air BnB!!!
