The Kink is a kink and fetish hotel in Schloss Calberwisch, a listed castle designed in 1875 by the architects Martin Gropius and Heino Schmieden, standing in a secluded 5.4-hectare park in the Altmark between Hamburg and Berlin. Its idea is to combine kink with rest and wellness: a holiday where guests can live out their passion and their fetish.

There are seven suites of 100 to 150 square metres, each with several rooms, a fully equipped kitchen and its own theme and furniture, from a romantic suite to Tied Up, fitted with BDSM furniture and a large bondage tower with a winch. The house also has a spa area, a lounge and bar, and extensive grounds with a horse and goat stable. The house rules ask for open-mindedness and make consent non-negotiable, and guests who are not registered in the booking may enter only with prior approval.
