Arte Luise Kunsthaus
What began in 2008 as an “art lab” in a palatial (but condemned) 1825-vintage residential building has evolved into a livable museum-cum-hotel near Berlin’s government district. Today, the revitalized old property (along with a new wing that opened in 2003) houses 48 completely unique rooms, each conceptualized and created by a different artist. The results—which vary in size from sumptuous suites with 13-foot ceilings to small single-occupancy garrets—are wild: there’s the Cabaret room, red-lit and decorated with mannequins in racy lingerie; the Loop room, where the walls and ceilings as well as the floors are completely covered in carpeting; and the Nest room, festooned with sculptures of giant eggs and bird beaks.
