Well the day we were getting ready to go check-in, he cancels saying we were a "no show" with no refund despite multiple written records of his confirmation that we'd be there the second week.
I asked AirBnb to refund us for half, and over and over they'd transfer between agents who had no f*cking clue about the case and just kept regurgitating some cancellation policy and ignoring my obvious evidence.
Finally I took to the social airwaves and kept calling over the course of a week and they eventually relented and refunded something.. and the best part, they never apologized once, in fact they made some absurd 6-year old passive aggressive comment about still being right but they'd refund me anyways -- and the refund was less than half.
I get that two-sided markets are tough, but even having the slightest decency and empathy during the matter would have made a world of difference to me.
