I had booked a single room. I was made to wait in a pub for a couple of hours. Sarah then came and said there was someone else staying in the single room. When I asked why she double-booked it when I had reserved it 2 weeks ago, she said I could stay in a Double room "as a favour to me". The next day, I was told I could stay longer in the double room but I would have to pay double. I refused and was moved into the single room which I had paid for. I had to put my clothes to dry in the room because there was no other space.The room wall heaters don't work so I had switched on the Heater. Sarah has come to show this room to another future tenant when I had gone to the shops. She sent a message saying there was smoke coming from the room and had to open the door. She then took away the Heater. When I came back, I saw the message and asked where the smoke was coming from because there weren't any clothes near the Heater. She started screaming that I shouldn't put the Heater on if I am not in the room and "who will pay the bloody bills". I told her that the wall heaters don't work and it is near freezing. She said nobody else was feeling cold and I felt cold maybe because I am from a warm country. She gave back the heater. 2 days later, I was sleeping in the evening because I was working the night shift. Sarah knocked the door. When I didn't answer, she unlocked the door with a spare key and came in. I jumped up and said I needed to sleep and she said she came in to ensure the heater was off. After this, she kept sending messages that I should do the Airbnb review in front of her. I escaped 2 days later by checking out at 5 am.
