Jeanne's place is very well located, just at the southernmost corner of the Parc des Buttes-Chaumont, with Belleville in very comfortable walking-distance.
There are also a lot of nice places nearby, we loved the "Bolibar" for example.
The apartment itself is just like in the pictures, very nicely decorated and cozy. There is even a balcony and a fully equipped kitchen.
The only thing that noise-sensitive people should keep in mind is that is is directly next to a street and that it is not super quiet due to that.
Jeanne was very responsive and helpful.
We loved our stay there and if we come back to Paris, we will see if Jeanne's place is available ;)
