We stayed in Celine's appartment with three children for a week in August. The location is optimal, walking distance to Arc de Triomph, Eiffeltower and Champs Elysee. The street has a lot of cafes, but the appartment is in the rear building, so it is nice and quiet. A small supermarket is within 5 minutes walking distance.
The appartment is spacious, clean and the kitchen offers everything you need to cook for 5 people.
Celine was a very nice host, communication was easy and pleasant.
I definitley recommend Celine's appartment!
