We enjoyed our 3 night stay with Martine and Karim. It’s an excellent location, close to the metro, but quiet at night, and easy to get to Gare du Nord and Charles de Gaulle airport. Nearby streets are bustling with lively bars and restaurants, and excellent bakeries. The breakfast provided was a bonus. The apartment itself is small, but adequate for a couple for a few days. Very good street market on a Tuesday by Corvisart metro. We would definitely recommend Martine and Karim’s place for a stay in Paris.
