I booked an apartment, the payment was debited. The owner confirmed the arrival, and then wrote that the apartment was not available. She offered another apartment, but a completely different district and a level twice lower. I asked for a refund money. The host did not contact for two days. I had to contact support and ask to resolve the issue with the return of payment. Only after 4 days they finally helped me solve everything. It's a pity the time wasted that I had to select another apartment and wait for a refund.
