This is a wonderfully located apartment, with complete services for kitchen and very comfortable bedrooms. Even though these have windows out to the street there was no noticeable noise coming from outside. The presentation is accurate and the welcome from Jean-François and Génevieve was superb. They were very rapid at answering to concerns we had. I would qualify our stay as GREAT if it were not for the fact that the Wifi never reached the upstairs rooms, and it was spotty even downstairs. The hosts came quickly to try to fix it, but a new router that they placed did not do the trick and from then on we had to rely on our cellular service. Now a days virtually everything you want to plan for, be informed about or schedule goes through internet service so this was an important problem. We would return to the apartment for sure.
On the other hand: location, location, location. For a visitor to Paris, first time or recurrent (like us), I don't think you can get any better than this location, in the heart of the 6eme, with all sort of restaurants, merchants and transports within very short walks, you really don't need anything else.
