"You’d be forgiven for mistaking this bold design hotel inTjuvholmen for one of the neighborhood’s many art galleries. Billionaire owner Petter Stordalen is a sponsor of the Renzo Piano–designed Astrup Fearnley Museum of Modern Art, which allows him to borrow worksby the likes of Andy Warhol, Cindy Sherman, and Jeff Koons from its collection to exhibit in the hotel. (Your room key grants you free admission to the museum). In addition, the former director of Norway’s National Museum of Art curated original pieces from international and local artists for all 118 of the hotel’s private spaces. The rooms—which have floor-to-ceiling windows, many overlooking Oslo Fjord—blend neutral blues and grays with sexy gold accents; amenities include interactive TVs showing “art on demand,” Norwegian wool slippers, and woolen blankets for wrapping up on the balcony. The Thief’s commitment to creative expression also extends to the soundtrack: Twice a month, the hotel enlists Scandinavian musicians to perform acoustic sets in its lounge or, during the summer, the rooftop bar."
