8. Crazy Horse Hotel, Dalat, Vietnam
This appropriately named Vietnamese hotel started off as the private residence of architect Hang Viet Nga who let her imagination go wild. Made from the base of a dead tree, the house is full of ladders leading into hidden nooks and tight tunnels. Not only is it one of the most unique hotels you’ll ever stay in, but it also won’t break the bank. Rooms costs as little as $22 USD per night.
