Elies Sifnos Resorts, Vathy, Sifnos $$$$
Concierge.com's insider take:
A rarity in the Greek islands, the Elies sits directly on a beach, one that until 1997 was accessible only by boat. The shore curves around Vathi Bay, which is home to little more than the resort and a small fishing community. Built in 2004, the resort differs from other new Cycladian hotels in that its 23 rooms and 10 villas are spread out over so much property, it seems to form its own village (with the town square replaced by the pool patio). Because of the abundant space, the rooms are large—ten of them even include their own private pools. There's a spa, tennis court, and gym, a gourmet restaurant featuring Mediterranean cuisine, and daily olive- and wine-tastings, although the main activity seems to be finding a beach chaise lounge that will allow for optimum viewing of the yachts anchored in the bay.
Closed mid-October through mid-May.
