We are three 60ish ladies who really enjoyed staying at Christophe's place. It is an easy walk to both Gare du Nord and Sacre Coeur and opposite a metro station. The apartment was great for us - it is on a very busy street but we didn't hear any noise at night with the windows closed (April). It is in the middle of a big city, so normal street- wise precautions are needed. Christophe was very organised and welcoming. All the family things are in the apartment and we appreciated the fact that we didn't have to shop for basics such as coffee, oil etc. There are many local restaurants nearby - too many to choose from! We had a great mini break in Paris.
