We’ve seen shipping containers used in the build of Aether’s San Francisco flagship store, and now the shipping container concept is used in a unique hotel experience called Sleeping Around. Currently located in the Belgian city of Antwerp, the pop-up hotel is made up of four luxe hotel rooms, which guests find using a GPS device. Each room is made from a recycled 1950s 20-foot shipping container, each appointed with a floating box-spring bed, Hansgrohe rain shower, iPod docking station, Dyson air conditioning and minimalist light fixtures. Two additional containers feature a breakfast/lounge space and a sauna. Travelers can track Sleeping Around’s current location on the company’s site and book accordingly.
