Billed as “a masterpiece of modern design”, the D-Hotel Maris in Datca, Turkey certainly boasts fine designer credentials. But it also offers plenty of natural beauty. Perched on the spot where the Aegean and Mediterranean seas meet, there are five private beaches for guests, with silky white sand imported from Egypt (it’s gentler on the feet). The top suite is the 1,017 sq ft Exclusive Villa, which has its own separate entrance, swimming pool, a private hammam and 24-hour butler service. Take time to catch the sunset, which locals claim is the most beautiful in the world.
