You mustn’t miss the Grande Dame of Athenian opulence. A Starwood Luxury Collection Hotel, this historic property is where Downtown Abbey meets the Acropolis. You’ll know you’re in the most glamorous address in town by the affluent crowd passing through its doors. Straddling fashionable Kolonaki and Syntagma Square, this hotel is quite over-the-top, with Greek marble literally everywhere. Fabulous.
