Ktima Lemonies (ktimalemonies.gr; doubles from €119) is hidden in the hills of a sprawling estate covered with olives, lemon trees, and Muscat wine grapes. Open April to September, the cluster of converted farm buildings can house up to 10 guests. Farther north, you'll find the stone houses of Onar Villas (onar-andros. gr; doubles from €169), a resort at the confluence of forest, river and the white-sand Achla Beach. The hotel, also closed during winter, showcases local materials throughout—from the reeds in the ceilings to the olive oil in the bath products.
