Sebastien’s place is pretty much perfect. It’s in the middle of a lively, non-touristy neighborhood with a ton of cafes, bars and restaurants, but you’re still only a 20 minute walk from the Seine. Very close to multiple Metro stops. We had a slight mishap with a window on the second day, and Sebastien responded to our message within minutes and was very understanding and helpful. The apartment itself is spacious and lovely — we had four adults in our group and it was quite enough room for all. A+ experience all around.
