I don't think I can add much on to what others have said. Jean-Claude's apartment is well appointed, centrally located spot AND DID I MENTION THE VIEW?
Yes I heard plenty about this view but when my wife, son and I entered the apartment and looked out I still couldn't help but let an involuntary "Wow" come out. The Eiffel Tower is right there in the middle of it. No picture can do the view justice but you will still make your FB friends eat their little hearts out with the sunsets you will post.
I should mention the air conditioning because anyone who's going to Paris in the summer knows it can be hard to find and even harder to confirm that it is real air conditioning. The AC is real at this place and works well. We just missed the worst of the August heat wave and didn't need to use it that much - just to cool down the apartment a bit at the end of the day. We never had it on while we slept as the cool night air from the bit windows was much more pleasant.
Rent this place - it is so worth it.
