Julien made our Air B&B experience an exceptional one! He messaged us a few days prior to our arrival, giving us perfectly detailed directions on how to get into the building (which is conveniently located directly across the road from the underground rail station). The flat is clean and charming with a lovely view of the neighborhood. Yes, there is a winding staircase as you walk up 7 flights, but it hardly can be considered a "con", as the "pros" of the place are so wonderful. We felt like we were a part of the true Paris experience. Thanks, Julien!
