Christine was very helpful and made sure we had all the information we needed. Her home is perfect for a family and has a good kitchen so you can be self sufficient for cooking (as eating out at restaurants in Paris is very expensive, yet shopping for food is cheap). There is also a lounge room, and separate bedroom for the kids. The main bedroom has a door which opens out into a beautiful courtyard.
The location is very central, a short taxi ride from the Gare De Nord, and a 5 minute walk to the metro with trains departing every few minutes so you can get into Paris central in 20 minutes. The metro is much better than I expected, better and cheaper than using busses for sight seeing. There are also many shops outside (eg: a Fromage shop and a bakery) and across the road is a large park for walking or jogging, this all adds to getting the sense of French culture and its right outside your door !.
The unit is on the first floor and there is a lift so you don't have to drag your bags up the stairs.
We felt 'at home' and very safe and secure here and would highly recommend you stay here for a good overall experience.
