Perfect place for traveling with kids. The place is literally next to gare du nord which is convenient if you come to Paris by train but also during your stay: the metrolines from here take you anywhere in Paris in just a few minutes. All the facilities that you might need for kids (in our case a 1,5 year old) are there. And the place has a great atmosphere. One improvement point: one of the 4 adult size beds mattresses is very thin. This is probably ok for a kid to sleep on but in our case it was just a bit too thin for an adult to sleep comfortably.
