Marielle is an excellent host, always willing to help, providing accurate instructions if you have questions regarding anything. She and Arnaud (her son) are very nice people.
The place is very close to everything, in the neighborhood are a lot of bars and restaurants, the Metro and RER are a 5 min walk, the Arch of Triumph is a 15 mins walk away, and you can get to the historic centre of París by metro in less than 20 minutes.
Very calm and beautiful neighborhood. J' recommande!
