Trendy boutique hotel, quiet at our initial check in. Rooms are a little small but probably expected and worth the trade off being in the heart of Marais. Within walking distance you can get to restaurants, shops, bars in a safe location. The Seine is also very close. Our balcony door window was defective so we were moved the following day and they gave us a bottle of champagne which was nice. The pool is romantic and no one was using it, so we had it to ourselves.
The only annoyance was the nice bar was booked one evening for a party. Im not sure how often that happens, but can be quite a racket as the loud music loomed over the hotel and into the rooms above the solarium room.
