With its glass floors, floating fireplaces, and eccentric chandeliers made from musical instruments, this trailblazing, über-modern chalet hotel has won a clutch of design awards since its opening in 2010. (World-renowned local architect Heinz Julen is behind the design.) In stark contrast to the picturesque streets and chocolate-box chalets of Zermatt, Backstage offers a harsh urban setting: high-tech interiors of walnut, velvet, distressed leather, and brushed stainless steel. For the ultimate design experience, request one of the six split-level, cube-shaped lofts when you book. In the basement, the entertainment space Vernissage contains an art gallery, cinema, and live music venue. Guests can tuck into highly innovative Michelin-starred gourmet dining at the After Seven restaurant, but the real pièce de resistance of the property is the innovative wood, steel, and glass spa. A unique three-hour experience is offered, comprising seven treatment "cubes" representing the seven days of creation, plus a host of special effects, including whale-song, live streaming from the Hubble Space Telescope, and movement-sensitive music and video installations.
