I would give Martine 6 stars if I couldn't. Stay here if you come to Paris and avoid the middle of the city. Belleville is such a gem. Check out la jordaine and le trois 8. In the apartment is a book of suggestions and tips, as well as manuals for everything in the space. In my two months bouncing around Europe, this is the best place I've stayed and if I make it back to Paris this is where I will be.
