My girlfriend and I spent 4 nice days at Bastien's place. Ok, the room is not fancy, quite basic, but that's the standard of Paris for that price and plus it is quite spacious and very silent and dark at night/morning (good choice for a lightsleeper like me!). Bastien is a nice person, he speaks a perfect english so you can have enjoyable conversations but be sure that he will totally respect your privacy. Last plus: the neighborhood is well served, few minutes from Montmartre and the metro station is right in front of the door, unbeatable!
