Great stay at Sylvain's apartment.
Sylvain was there to greet us and gave us a tour of place as well as advice on the neighborhood.
I highly recommend Sylvain's listing. Simple, clean with everything you need should you decide to stay in rather than eat out.
The apartment is in a good location as it is really close to Gare de l'Est and Gare du Nord. It is not in the most glamorous district of Paris but it is less than 7 metro stations from the city center. Not to mention that it is a 5 minutes walk to the Canal St Martin.
Thanks Sylvain for the warm welcome!
