On the Athens Riviera, 30 miles from the city center, the Sixties-era Astir Palace has been brought squarely into the 21st century as a part of the ever-luxe Four Seasons family. Its distinctive terraced construction means the views from the spacious balconies are still as abundant as ever; the interiors are sedate compared to the Sixties but quite stylish, and they’re faultlessly luxurious. Creature comforts are plentiful — the pools, the spa, the sea-facing cabanas — and among its several bars and restaurants the flagship, Pelagos, is the proud recipient of a MICHELIN Star.
