Our stay was wonderfull, Fred and Aurelie was really great hosts.
The apartment is exactly as it appears in the annunciation and the hosts help you with everything you need.
There are two metro stations really close to the apartment, being one of them(Republique) with almost all of the metro lines that you need to know Paris, a lot of supermarkets, pubs, restaurants, fast food and other options.
The only two things that you need to have in mind is that if you prefer shower instead of bath, you need to be a little bit flexible to fit under the shower and also kitchen and living room has no courtain.
But everything was better then expected, if I go to Paris I would definately stay in their apartment.
