Jean-Claude’s apartment is fabulous.
It’s located about a block away from Rue des Martrys, which is a wondrous market street, full of cafes, bars, boulangeries, patisseries, food stores, etc. Sacre-Couer is about a 10 minute walk. The apartment is very quiet and clean and is beautifully furnished and decorated. Highly recommended! I will definitely stay here again when I’m back in Paris.
