We were boiling in the apartmnet, we couldn't sleep because of the hot weather. We contacted the owner to provide an A/C but he refused. We decided to leave the place after couple of nights to a hotel. We told the owner that we are leaving because of the heat and agreed with him to leave the key; so I sent him change request in the app to change the period, he declined our request to change the period because he doesn't want to refund the nights we did not spend in the apartment!!! We have been charged the full amount!!!
