We had a wonderful stay at Mathilde's place. The apartment itself is great, much bigger and better than I expect (I think the pictures on airbnb are under reality) The apartment is basically a 2 multi-room apartments together, with an extra basement. The space is more than enough for 10 of us. Also the location is great too, 2-min walk to Notre dame and also with lots of restaurants / bars nearby. Highly recommended for group travelers!
