The apartment is in an excellent location and not noisy at all. It's wonderful and clean and has all the things that we (5 adults, 3 kids) needed to be comfortable for 4 nights. Communications with the team are easy and quick. Check in and out was a breeze.
The only thing that needed to be mentioned is the elevator is tiny and it does not start from the ground floor. So for people like us with lots of heavy luggage it was quite a bit of work in getting them upstairs to the 3rd floor.
Other than that, our stay in Paris was amazing, the apartment was lovely and we got lucky with the weather.
I would definitely recommend this place!
