Hostels can be boring, cheap, safe places to stay for a night. Of course, in Eli Roth's "Hostel" horror flicks, they can lead to torture and malice. This list leaps beyond the bare white walls and hard mattresses, while stopping short of chainsaws and blowtorches. But prisons and castles (moat included) make the cut of 22 cool and usual hostels, listed in no particular order. There's even a jumbo jet.
1 . Kadir's Tree House, Olympos, Turkey
Built as an actual tree house, Kadir's offers treehouse rooms, dormitories and private bungalows for two or three people. Breakfast and dinner are included, and Kadir's has two bars that open at lunch and close after the last guest leaves.
