In many countries, in that price range you can find everything. For example, last year on a cycling trip I ended up in an Albanian city on the one weekend a year when all accommodation is fully booked due to a festival. Lucky there was one remaining AirBnB host, and I rented his five-room house for 25€, fees included. He lived elsewhere, I had the whole place to myself (which was total overkill). Most of the other hosts, though unfortunately already booked, were offering rooms or entire spare flats for half that.
