I used to be a big fan of airbnb when it got started in the spirit to support YC companies. Over the last couple of years all my experiences have been crap. I've lost about $1000 in non refundable fees because I've tried to cancel hosts who had almost unlivable places.

The review system is gamed and the whole things feels like a giant scam now. I never use it anymore and back to reliable hotel chains that guarantee some sort of quality.
