Eliamos Villas Hotel & Spa

Twelve villas tucked into olive-dotted hillside above a hidden cove on Kefalonia's southern coast, each with a private saltwater plunge pool and terrace pointed toward the Ionian Sea. The owner is an interior designer, and it shows: poured concrete, raffia, bleached wood, none of the blue-and-white clichés you were bracing for. There's a small spa, open-air dining, and a sea-facing gym for yoga and Pilates. The Michelin Guide awarded it 2 Keys.
