Quite good option if you're planning to stay in Paris for a couple days or a week. The neighborhood is fool of shops, restaurants and bars. The apartment is 4 minutes walk from closest metro station, but it's quiet in the apartment.
It might be a bit uncomfortable to stay in this apartment if you have a lot of things. At least at my stay, there was no closet and every part of the apartment was filled with things of the owner. The doors within the apartment are not that easy to open or close.
All in all, the apartment is great. If you are planning to visit Paris and attend sightseeing spots it will be quite comfortable to stay here.
