The iconic hotel opened its doors in 1963 as the first major international hotel in Greece. A hub of the Athenian society, the 506-room luxury hotel will be turned into a Conrad Hotel with 280 rooms and 50 branded residences by Conrad and Waldorf Astoria. Both brands are also part of the Hilton family. The newly renovated hotel (at a cost of 130€M, and €145M for the property acquisition) is scheduled to reopen in 2024.
