This is certainly one of the worst experiences that I had with Airbnb. Ana, the host, informed us of the change of the apartment location the night before we checked in. The new location is right above the train station, with trains going in and out all day long and all night long. I was not able to sleep at all. The apartment was not officially listed on the Airbnb website, and we had to present to be "friends" of the host to get in and out of the apartment. Ana was slow in responding to my messages. Often it took hours for her to get back to a simple question. I would like a partial refund.
