Everything is perfect. We had a great stay, the apartment is well-equipped and the location is in the centre of Paris. It takes 10 minutes to walk from the apartment to Gare du Nord. Alice, Nathalie's daughter is so kind and gentle (and beautiful as well :) )
We had an issue with the key that had not asked Nathalie carefully before leaving, it was our fault and will take it into account for next time.
