If you're not a five star hotel kind of person, perhaps you'll like to take a vacation inside artist Joep Van Lieshout's colon at the CasAnus.
The CasAnus is a giant sculpture of the large intestine in which people can stay. Located in Belgium, CasAnus offers guests a comfortable visit, considering you're staying in a colon shaped sculpture. Inside there's a double bed, an electric heater, a shower and of course a toilet. To quote the owner of the park in which CasAnus is located, "[the] exhibition space does not aim to be an oasis."
If you stay at CasAnus, you'll also be able to view other sculptures and art pieces near by, as the land surrounding CasAnus is a private art site.
