Have you ever experienced a night in concrete pipes? You have the chance to experience that T3arc’s TuboHotel. It is a mini hotel located in Tepoztlan, Mexico and it was built from recycled concrete pipes. Although the rooms may seem small they offer a cozy living as well as some beautiful panoramic views of the Sierra del Tepozteco. And if Mexico is too far away for you, you can visit some of the bunker hotels in Albania, the idea is the same.
