The appartment is located in a lovely neighborhood by the Pere Lachaise cemetary and metro station, only few minutes walk from the Rue Oberkampf, which is full of restaurants, bar and cafes.
Quentin himself was very kind and helpful - I arrived a bit late due to a bus delay and he waited for me and explained me everything about the flat, neighborhood and gave me a key and wi-fi password. My bedroom was clean and you may smoke on the balcony in the living room.
