The apartment was not cleaned when I arrived, the linen and bathroom was still in used condition from previous tenants. It was not fit for use and I had to book an alternative at the last minute.
On top of that, the host refused to grant my request for a refund through Airbnb's channels. Rather, he tried to trick me into cancelling the booking on my end, after which he works refund me through another channel. This would have forfeited my right to a guaranteed refund. What his intentions were unclear, but such behaviour leaves guests open to being scammed. In short, there were several violations of Australian Consumer Law.
In the end I had to reach out to Airbnb support who provided me with a full refund, no questions asked. It was a very unsavoury and unprofessional experience and I'm glad to put it behind me.
