Cyril was a great host! (I didn't have a chance to meet Romain.) He was super helpful with directions and recommendations as well as coordinating with my arrival. He even invited me to join him for dinner. The apartment is also massive! As for the area, the Canal is a great neighborhood that isn't overly touristy, but still has easy access to the Metro as well as a number of great restaurants and bars. There is also a fantastic bakery at the closest intersection along with a grocery store just down the street, making the location even more convenient.
