Very unique and nice apartment, with a great and central location. Within walking distance, there are a lot of great sights like Louvre and a lot of restaurants and supermarkets.
Communication with Christine was easy and fast and we could even store our luggage longer (thanks for that!).
One addition: 2nd bedroom is a gallery with very low ceiling, where you can only sit and knee. So not convenient for tall people or people with back problems or e.g. pregnant.
