The host's behaviour was completely unacceptable and inappropriate. The host stated some extra charges on the flat's AirBnB page, but then when I arrived she claimed I had to pay a much higher price. She constantly pressured me into paying her, and insisted that I should pay cash and not through the AirBnB app. She then blackmailed me, saying that if I didn't pay her the amount she was asking me she wouldn't let me use essential facilities, like the kitchen and the washing machine. The situation got so bad that she made me cry. This same experience was shared also by the other lodgers, who were forced to pay her extra fees in cash. This situation made me feel completely unsafe in the house, and therefore I had to leave and cancel my reservation.
