Located on Athens' Agia Eirini, a perfectly situated and charming Byzantine-era square that is off the tourist trail, Perianth Hotel is a modern refuge in this ancient city. Opening mid-July, the hotel is the creation of three siblings—Konstantinos, Anastasia and Alexandra Sgoumpopoulou—whose career paths and passions cross merchant shipping, art, and fashion, and pays ample homage to the Athenian modern movement. A 1930s building has undergone a full transformation—one that sees Greek star-designers K-Studio take the reins, choosing terrazzo floors, marble furniture, and glass brick to convey contemporary Greece. The hotel also shares its space with the Zen Center Athens, a unique institution devoted to meditation, martial arts, yoga, and Eastern philosophy.
