My mom and I spent 8 days at Sylvain's and we had an incredible experience. His directions are very clear and easy to follow when using both public transit and/or taxi. The bed is very comfortable and the kitchen is fully equipped for cooking. The apartment is conveniently located near multiple metro stations (closest one is 3 minutes walk). This is a great place to stay to feel like a local and explore a less-touristy neighborhood in Paris.
