We never talk with the host before to arrive. I ve send a message and she reply back the day on our arrival,When we arrive at the flat we try to open the main door with her instruction (not clear, actually) and the door doesn't work. We make a wtp call, message to the host and Airbnb chat but no one reply back. After 3hours, it was cold and dark out, and Estephany seems to be disaperead we came to the bar to try to get Internet connection and ve decide to make a new reservation in a order to get a flat for the 1th our Night in Chicago. After 3h and half she call me back and after explain the situation she said then will refound us the ammount purchase for the other accomodation. She also got a problem with the door and want able to come in. And asked us to leave a back door open to her. We never had our money back, Airbnb support don t help us and the mánager in casé give us a response after 1week.we decided to open a casé Trough PayPal. Not recommend this host.
