We enjoyed the stay in Laure's apartment where we also found a bottle of wine for us as a welcome. The communication before our stay and for handing over the keys was perfect. If you arriving by train at Gare de l'Est it is not far away. We found it quite convenient to go the Gare du Nord using the RER B (one stop to Chatelet - Les Halles, 2 stops St. Michel Notre Dame). It saves you time to go to the city centre but you can also visit quite easily the Basilica in St. Denis - one of the earliest Gothic churches in Europe.
In the rue Faubourg St. Denis which is close you can enjoy Little India in Paris.
In the surrounding area, you'll find shops (e.g. MiniCarrefour) and a post office. Enjoy your time in Paris as we did. (Bien sûr, vous profitez plus de votre temps à Paris si on peut parler (un peu) français.)
