WellnessHostel 4000

This striking, modern building next to 17th-century granaries on stilts is possibly Switzerland's loveliest hostel. It adjoins a pool and spa with gym, various saunas and steam baths, and tea station. Sharp and stylish rooms range from six-bed dorms to swanky family rooms and doubles, and standard rates include the pool. 'Experience4000plus' rates throw in the gym and spa, too.
