We stayed in this apartment for 3 nights and had a lovely time! We really loved the location - it's in a interesting neighborhood, and is close to Gare du Nord (the main train station in Paris) and Metro lines. Extremely convenient! Mathilde was kind enough to let us drop our luggage off early, which was particularly appreciated after arriving on an overnight flight. The apartment is a few floors up a spiral staircase, but there is a small elevator that is about the size of two people or one person with a suitcase. Once we officially checked in a few hours later, the apartment was ready for us and set up with all of the basics we could have needed. Mathilde and Jean-Pierre's apartment is above the rental apartment, and they share an entrance. Mathilde was very accessible and responsive to communication throughout our stay. A few other things... the shower stall is basically located underneath one of the turns of the spiral staircase, so the walls near the shower spout are sloped and curved (which may be tricky if you are claustrophobic or very tall), and it drains very slowly. Also, the sofa bed (like most sofa beds) was a little squeaky and not super comfortable, but it was OK enough. All in all, a good option in a great area!
