The most uncomfortable experience I had with an airbnb place. The host Natalia was out of town, and the communication with the person that was in place was very unpleasant, going on hostile in multiple instances. Natalia was unresponsive to any of my messages. I had to spend a full day and my own money to try to get things fixed and get into the apartment (after a key I duplicated under the instructions of the person that let us in got stuck in the door). I understand how Airbnb apartments work, and never expect the level of service or cleanness of a hotel, but in this case, this was way out of what one can accept as reasonable behavior.
