The CasAnus Hotel offers couples an overnight stay for 120 Euros - around £100 - complete with a double bed, shower and central heating.Couples are flocking to the one-room hotel on an island near Antwerp to enjoy a night inside the colon, saying it's 'amazing.'It was originally created by Dutch artist Joep Van Lieshout, but the structure was renovated into living quarters and now sits on the grounds of the Verbeke Foundation Art Park.The hotel is run by owners Geert and Carla Verbeke-Lens, who say the hotel is 'extremely popular' with couples.'It is utterly silent and pitch black at night, so bring a torch if you want to creep around at night. It is as normal as sleeping in a slug-like space can be,' travel blogger Tom Hall wrote on Lonely Planet.(dailymail.co.uk)ANN.Az
