Suvretta House, St. Moritz
Tel: 41 81 836 36 36
Concierge.com's insider take:
Perched above a little forest in an area of private chalets about a mile west of St. Moritz's main villages (i.e. Bad and Dorf), Suvretta House has excellent views of the Engadine valley. The Belle Epoque castle has 189 rooms and suites, and shares some of the superior service, elegant modern decor, and chilly formality of its rival, the Kulm; including the bit about requiring gentlemen to wear a suit and tie in the evenings in the hotel's public spaces (though the Suvretta does have a lobby bar/restaurant where you can slouch in casual wear). The hotel has its own ski lift tied into the mountain network (it also stores the skis and entire winter wardrobe of regular guests), as well as an indoor pool, spa, and an elaborate children's program.
Open late June through late September and mid-December through early April.
