Kudos: Checking out I forgot some important items in my room, and the staff reached me by phone. Their lost-property procedure uses a sealed envelope with printed manifest. I bought thank-you chocolates.
"King room" okay for one person, would be cramped for two. Stylish but some usability flaws: mirror lighting poor for shaving; shortage of pegs or rods for towels. If you want to launder socks, the basin is small and its drain doesn't seal. Most functions (smart lighting schemes, TV, etc.) operated through a tethered iPad, but key functions (lights, shades) have bedside switches. Closet-niche with six hangars and room for luggage, but no stand. Drawer and safe beneath bed. Plenty of type-C power points around the room, no USB; desk has triplet A-C-G (U.S.-Europe-U.K.). Pump cleansers at sink and in shower. Room door does not self-close, but requires a strong pull. Sealed window.
Street entrance easy to miss because the hotel sign is elevated. Take elevator to lobby. Assisted self-serve check-in; pick your room type, pay city hotel tax. Several "fun living room"-style lounges with art and books, and bar/restaurant. Umbrellas for loan.
Hotel is one flat block from Gare de Lyon which, as a major hub, has escalators (most Paris Metro stations don't). Can be reached from CDG via RER lines B and D (11.80 EUR airport tik). Station vicinity has many hotels, restaurants, small grocery stores, ateliers; well-lit, feels safe, but has pan-handlers. Limited traffic, surprisingly quiet.
