The flat is very stylish, spacious and clean and had the full range of amenities. It's close to a few metro stations so it should be easy to get around (unless like us you're there during the strike) . There's a supermarket across the road open till midnight, and there are places to visit that are a short walk away like Pere Lachaise cemetery, Buttes-Chaumont park and the Chinatown in Belleville.
We found our stay very comfortable (except for the strikes) and would recommend to anyone visiting Paris!
