I had a bad experience with a host, i booked a room for the night but he wasnt there and would not answer his phone when i arrived i was told he didnt even live there i ended up staying in a hostel. After explaining what had happened to airbnb and after giving them a copy of my phone log and other travel documents to support my claims after a few days i was given a full refund and a £50 coupon off my next reservation using airbnb so in the end i feel they did compensate me and i am gratefull for their good customer service.
