Jean-Pierre's and Henri's place is a beautiful loft and very convenient to the Metro. We ended up staying only for a night in Paris, but it was the perfect place to rest. After a long day of sightseeing and exploration, we very much appreciated the a/c in his flat!
I could see how the shower door could be a bit of a squeeze for a larger person, but it worked for us. Also, watch out to not hit your head on the ceiling where the bed is!
