I recently had the terrible misfortune of booking an Airbnb location which is actually two units, an upstairs unit and a downstairs unit. The day I arrived it was so cold I could not sleep. Unfortunately the temperature controls are in the upstairs unit and not accessible to the downstairs unit. The host offered to bring heaters but a small space heater does not remove cold that oozes out of the floors and walls.
Immediately I then began to experience the noise from the unit above. Parties until 3 am, loud, raucus, wrestling matches with people slamming each other into the floor boards. Night after night after night. Finally I messaged the host after speaking to them verbally and I said that I had, had enough and I wanted my money back. He refused despite the fact that many others had complained about the same thing. The noise, the being at the mercy of the upstairs guest.
I have complained to Airbnb many times. They have the proof that this happened. They know it has happened to others but they will not put through a refund.
How do I escalate things from here?
