Sylvain and Marie's place was the perfect place for my teenage daughter and myself! We both slept comfortably, and the kitchen had everything we needed to cook our meals (and given that we were there two weeks and I cooked most of our meals, I can definitely attest to that!). The fact that it was on the main floor was a huge plus since we stayed there for two weeks and had more luggage than we might have otherwise, but there is a stairwell in the apartment itself that curves to the level with the beds and bathroom, so be aware of that if you want something without any stairs at all. They weren't there to check us in, but their friend Carola was there, and she was very nice and helpful, and Marie checked on us a couple of times while we were there, and she was very responsive to us, so their not being present wasn't an issue at all. I really liked the neighborhood; it wasn't extremely touristy, but it was lively, so it was a great neighborhood for us to settle into. The apartment was also right near a metro stop, so it was very conveniently located in terms of travel around Paris. We were also surrounded by grocery stores and restaurants, which was great as we came home every evening from exploring the city. I highly recommend Sylvain and Marie as hosts in general and this apartment specifically!
