Spend the night in the cabin of a dockside crane that you can rotate, in a tent hanging from a tree, in the depths of a salt mine, an igloo, a round house that turns with the sun, a survival pod from an oil rig platform, a giant hamster cage, a coffin, at the top of a lighthouse, in a cider cask, a glass pyramid, aboard a plane, on a private island, in a house anchored to the top of a factory smokestack, in a red cube in the countryside, in a train, a chapel or a prison ... Our selection of hotels, B&Bs, self-catering cottages and other unconventional lodgings, the result of five years of research, will let you spend a night unlike any other, which you will never forget. More than 250 unusual properties, starting at €10 a night.
