J & JP were great host. Very easy and quick check-in. Their apartment is designed with great tastes and located in the very heart of the city so you can reach every part of the city quite rapidly. Easy access to the metro station (5 mn). You can even walk South along rue du Faubourg Saint-Denis to go the Grand Boulevard and continue on your right to Opera ! And if you want to experience the French food, who will not ? ;-), there are plenty of restaurant in the street.
