Just when you thought you'd seen it all - tree hotels, salt palaces, undersea lodges and enormous boot-shaped bed and breakfasts -- something new comes along that tests the limits of accommodation possibilities. Located in Tepoztlán, Mexico, is the Tubohotel (shown right), a unique experiential property that allows guests to sleep in massive tube pipes stacked like pyramids.

In line with ecotourism, the tubes are made of recycled tube pipe materials. While this may sound like you'll be sleeping in a sewer, the company claims the experience is actually very comfortable. The rooms each come with a queen bed, fan, desk light, storage compartments under the bed, a towel rack with towels, a plush comforter and soft sheets. Furthermore, the tubes are apparently quite warm. Or, as Tubohotel says, the rooms maintain a "comfortable, almost tubo-licious temperature during the day and night."

While you won't be able to bathe in the room, the property boasts two clean, spacious bathrooms with hot water, private showers and toilets, although you will have to bring your own robes and slippers.

No matter how nice the rooms at Tubohotel are you're not going to want to spend all day sitting in a pipe. Luckily, the hotel also has an onsite Infinity pool and can arrange for cultural cooking classes with celebrity chef Ana Garcia. Nature activities like mountain climbing, hiking and biking are also abound. Not to mention, a bar and restaurant are coming soon to the property.

Prices start at 300 pesos (about $24) per night, based on double occupancy. Click here to learn more or make a reservation.
