We thoroughly enjoyed our stay at Jean-Daniel's. The apartment is ideally located in a lively yet village-y part of the Marais, with everything we might need right on our doorstep. The living room gives onto a side street with some street noise, although nothing unusual for the location, but the bedrooms both give onto the quiet back side of the building, and we found the apartment to be a wonderful respite from the bustling Paris city center.
The apartment is large, airy (we were there for record-breaking high temperatures and the bedrooms remained cool), and charming, even more so than can be expected from the pictures. The kitchen was well-equipped.
Communication could not have been easier, as was the check-in and check-out. The apartment was spotless when we arrived. Jean-Daniel provided us with all the information we needed well ahead of our stay, and we were able to settle in right away. We would love to stay here again next time we are in Paris.
