Katikies Santorini - Pelagos House

Whitewashed rooms spill down the volcanic cliffside in Oia, each with a private terrace angled toward the caldera. This boutique hotel holds a Michelin Key and a Forbes Four Star, and the design earns both: spare interiors with antiques and marble kept deliberately modest, so nothing competes with the view. Three infinity pools make it easy to stay planted for the day, with dining options ranging from poolside casual to an open-air terrace restaurant. No one under 13 admitted.
