Jean-Marc is, as you know, a superhost. Very nice and easy-going. The building is beautifull, very old and whit it's own history, just close to another where Marie Curie lived once. It is Very close to St. Martin's canal, and really close to one of the most beautifull parks in Paris. The room is big and it has a little balcony from where you can see the roof of Paris, a great view!
Everything was great in our stay, we recommend it without doubt!
