Very Parisian chic apt, close to very nice restaurants and cafe. Though quite a walk if you want to be at the center (louvre and surroundings).
The picture showed quite well the place, however keep in mind that this os the actual home of the host, therefore expect personal things (photo's, food, etc) to be present throughout the apt.
Host is extremely flexibel and friendly, responds quickly. Check in very easy. 15 min walk from gare du nord.
