I booked an apartment in NYC for 21 day. Upon arrival I found that the place was dirty and in not livable condition. I canceled my reservation immediately even though I didn't have a place to go. Later on Airbnb refunded only 42% and stated that the rest of the amount is completely up to host. It was obvious that the host didn't want to refund. End of story. I lost money, had to find a place to stay and had no help from Airbnb at all. I wish I would read more reviews here before booked the apartment. Booking through Airbnb gives you a good chance to lose your money and ruin your vacation.
