Very good and cozy apartment. I stayed 5 nights and Pierre, Enguerran's friend, did the check in and check out in flexible times (and he was on time in both opportunities).
He showed all that we needed in the apartment and Enguerran has a guide with practical information about neighborhood (supermarkets, restaurants, metro, etc). As mentioned in other reviews, access to metro is easy - and if you like to walk, it's a nice location too, because you can go to most of the attractions walking (and return by metro, or vice versa).
The apartment is not very large (especially the shower box), but is very functional. The street is very quite in the night. I was able to use the kitchen accessories to cook every day, which allowed me to save a lot of money :)
