t the southernmost tip of mainland Greece, the secluded Mani Peninsula is home to quiet beaches and quaint hill towns. The fishing village of Gerolimenas is located on a small inlet where rugged cliffs wrap around a sheltered bay, and here, a historic landmark has been cleverly converted from a bustling grocery store into the sophisticated KaSeas Boutique Hotel. Like many of the older buildings in town, it’s sturdily built of native stone. But unlike most, the hotel enjoys privileged waterfront access: across the street from the entrance, KaSeas has a private beach club-style setup, with an open-air bar and a row of umbrellas and chaises right on the village’s natural harbor.

Most rooms have dazzling sea views, too, save for a handful that overlook an interior garden. With exposed stone walls, vaulted wooden beams, and poured concrete flooring, they’re atmospheric and dramatically illuminated. King-sized beds, Nespresso machines, and marble bathrooms are standard features. A few loft suites come with large furnished terraces, and other suites have open-air hot tubs or ocean-facing balconies. The hotel’s indoor-outdoor restaurant, set across the building’s stone terraces and especially inviting when candlelit after dark, is popular with locals; by day, guests enjoy trips around the coastline’s caves and crystal-clear waters on the hotel’s boat.
