Coco-Mat Eco Residences Serifos

The mattress company that spawned a hotel brand is a real concept, and the logic holds on Serifos: these converted miners' cottages on a quieter Greek island are built around the promise of a good night's sleep. Stone walls and contemporary interiors sit together without fighting, the bay below is protected and genuinely calm, and the lounge bar pulls triple duty as cocktail hour, breakfast spot, and dinner venue. It is selected by the Michelin Guide.
