This is a very nice Airbnb. Dehlia is very sweet and helpful. She gave us a lot of nice suggestions for places to go to and welcomed us with some fruit and jam when we arrived late in the evening. The place is very clean and nice and is close to some superb bakery shops and bars/restaurants. The area is calm and very beautiful with walking distance to Sacre Coeur. It is also possible to walk to Gare du Nord in only about 10-15 minutes. The apartment is located on the ground floor with the windows faced towards a small street; it wasn't a problem for us but it might be if you are easily disturbed by noise.
Great stay!
