Really cute and nice appartement, near one of the most important subway/RER station. Even though a lot of bars and shops were near the place, it was super quiet inside since it was on the top floor. Be advised, there are a lot of steps to climb in order to reach the flat (we did it with 4 suitcases, 1 big stroller and our 3 months old) but it's doable ;)
Bert was super accessible via messages and all the indications to reach the appartement were clear. We really appreciated our stay there :)
