My family, including 3 teenagers, loves the Montmartre area of Paris. Sacre Coeur at night is beautiful (and a party scene!), the artists markets are fun, and the area is full of artistic and literary history. Nathalie's place is perfectly located at the bottom of one of the Sacre Coeur many flights of stairs. The plaza below is a little loud in the evening with the windows open, but with the windows closed, there isn't much street noise at all. We have stayed in two other AirBnBs in Paris at this price point, and they were all tiny by U.S. standards, but Nathalie's place has good sleeping space for 4-6 people, and is very charming. There are at least three metros on two different lines nearby, and it takes only 20 minutes or so to get to the other major sights in Paris. We would stay here again if we are lucky enough to get back to Paris.
