This Upper East Side boutique hotel, a sister to the world-renowned Hotel Plaza Athenee in Paris, possesses a deep-rooted commitment to service, luxury, and sophistication. Rooms are sumptuous, with classic European decor and gorgeous bathrooms. The bar and restaurant are intimate and romantic, serving excellent fine-dining fare and cocktails, while the spa and fitness center provide charming spaces to relax and rejuvenate. Above all, though, is the hotel's dedication to service, made evident from the outset with a sit-down check-in, and continued throughout guests' stays by the excellent Clefs d'Or concierges. It is no wonder that both Princess Diana and Elizabeth Taylor have called the Plaza Athenee home.
