the apartment is just at perfect location, really in the center of Paris. The metro station (as well the Louvre) is just in front of the door! Eric is a wonderful host, though I didn't meet him personally (I finally postpone my arrival and it was my father who checked in). Eric replied so quickly even I really asked many questions...
The only little point I want to state is in the room with two beds, we couldn't find any cardboard to settle down our cloth. I had to folded all the cloths in the luggage, which is not very convenient.
