We stayed at Fabien's place for 4 days. Everything has been perfect: the apt is small but so cozy and amazingly furnished. We didn't meet Fabien himself, but he gave us speed answers every time I wrote him. He also left a useful guide about the house and the city!
The place is 10/15mins far from the center and just 3mins walk from the metro station. The neighborhood is quiet, with supermarkets and all kind of restaurants.
I would definitely recommend it, and if I'll come back (and I will, I fell in love with Paris!) I'll book again this lovely place.
Merci beaucoup Fabien!
