The host kept telling me to communicate with his mother off of the Airbnb app. I felt extremely uncomfortable with this, and with someone having my personal information. When I told the host Alexander I didn't want to communicate that way, he didn't listen. At check out, his mother and I agreed to a time and she was an hour late and didn't respond to my text messages. The agreed upon time was confirmed in a written text, so there is no way anyone should have gotten confused. I was forced to leave on my own or else I would miss my train. When I brought it up to Alexander, he refused to help me or answer any of my questions. Communication with this host is awful and unsafe.
