We were 4 people (including 1 teenager) and we had a wonderful stay!
Thibault and his wife were very friendly and made us feel like home from the first minutes. The apartment is placed on the top floor, has 3 bedrooms (1 of them is rather for a smaller child, so our kid slept in the living room). There's everything you need on your vacation in the apartment. It has big terrace perfect for breakfast outside and the bbq :). The place is 5-10 minutes walk from Jourdain metro, which directly connects you with the centre of Paris.
We highly recommend this place for people travelling to Paris.
