Yes, of course by airbnb. The only message I got by e-mail was that they couldn't rent me that place with no any explanation.
Here is the message:
Gospodarz Adriagate Travel Agency nie może już przyjąć Cię w swoim domu, ale jesteśmy tu, żeby Ci pomóc
I think this process of reservation is really poor in airbnb. Especially waiting now for money return 15days.
Maybe you should check if the place is available before taking the money.
