"Behind an iconic red door between the Place de la Concorde and the Champs-Élysées, this Jacques Garcia–styled hideaway in a former Duc of Morny mansion feels like an extravagant private home—Second Empire touches such as parquet floors, crown moldings and cordovan leather paneling frame 40 spacious rooms (minimum 430 sq ft), while public areas include a 3,000-book library, a fumoir overlooking a leafy courtyard, salons with plush banquettes, a 52-foot pool, a small spa with a hammam, and the three-Michelin-star Le Gabriel, where chef Jérôme Banctel reimagines French classics; practical touches range from USB cords for all brands to an oversize minibar and a chauffeur-driven courtesy car for guests." - Mary Winston Nicklin, Lindsey Tramuta
