The host was away travelling and didn’t leave a key for me to get into the flat. In her message before my arrival, she said the key was inside the flat however the door was locked and there was no way to get into the flat. She had not provided a phone number so I could only contact her via Airbnb and she didn’t respond until the following morning. I had no choice but to stay at a hotel instead (I arrived quite late at night). When I asked if I would be able to get into the flat the following day (I had booked three nights), my whole booking was cancelled and I didn’t get a proper explanation of what had happened.
I did get a full refund but I do not feel that it compensated the stress and wasted time that this situation caused.
