Unit was already occupied when I arrived. Was treated like situation was my fault when host said, “I can tell you are not happy why don’t you cancel and I will refund you”. Who would be happy to not get what they booked and paid for?!?! Host said I needed to cancel on the app. But I called Airbnb support and they said I would only get the cleaning fee due to the cancellation policy on the listing. The reservation had to be cancelled by the host to get the full refund but he repeatedly told me I had to cancel. The real problem is the host had let someone else in my booked unit. Unfortunate situation that could have been avoided by proper procedures by a professional business.
