This is a Paris palace hotel that still feels like it belongs to an art collector rather than a committee. The rooms mix bold color with Art Deco lines, the bathrooms are basically one giant mirror, and the location a few minutes from the Arc de Triomphe means you can walk to the Champs-Elysees and back before dinner. Staff get remembered by name on return visits, which for a hotel this size is not a given, and the concierge team builds itineraries good enough that one guest joked they should skip the trip-planning apps entirely.
The room you get isn't always the room you booked. More than one guest was walked through a beautiful suite by a butler only to be reassigned somewhere smaller after a booking mix-up, and check-in ready times of 3pm or later come up often enough to plan around. A few rooms have had real maintenance issues too: air conditioning that took days to fix, a bathtub that wouldn't fill, wifi that dropped the moment you left the lobby. None of it is universal, but at rates north of €2,000 a night it shouldn't happen at all, and the fixes, when needed, come slower than they should.
Book it for the location, the art, and a staff that treats returning guests like regulars rather than reservations. Skip it if you need flawless room mechanics on night one; ask for a courtyard or upper-floor room away from the bar noise, and confirm your room type in writing before you arrive. For a first Paris palace stay, or a fifth, it still earns the trip.
