Large, unique place right in the center of Paris (or so it feels). The apartment is the perfect hybrid between cost apartment and something out of a retro design museum.
Mikael was very helping with his neighborhood recommendations as well as any concerns regarding the place/moving in.
The only negatives would have to be the 5 flights of stairs (which you get used to) and the rather slow internet. Other than that, I would totally recommend his place to anyone wanting to experience Paris :)
