Very nice and charming appartment, perfect located in a very interesting and busy area of Paris close to Sacre Coeur.
It was clean and spacious, comfortable to spend some rainy evenings there and calm at night and the view from the tiny balcony was amazing. We could do a lot of activities on foot but it's also close to the Metro and only a short walk away from the central stations (Gare du Nord and Gare de l'Est).
Jean was a nice host. Absolutely recommandable.
