The location is amazing ! I lived in Paris last year for 5 months, and I believe this is really one of the best areas to stay. The apartment is very small, but it's comfortable and a perfect home base if you plan to spend your time exploring the city/area. Nathalie and her son, Max, made everything very easy for us, and although we had very little communication, I felt they were always available if I needed anything.
Would recommend !
