Matthieu is a great host, appreciate and infinetely kind, his place is on a well-known street for its typical French 'bistrot's, right next to his building you'll find a supermarket where you can buy everything you need (if you want to spare some money, not spend everything on restaurants...), and the neighborhood is young and lively!
Extra: a lot of silence, if you need to study or you have troubles sleeping, you won't hear a thing staying in his apartment, which is so rare in a big city like Paris!
