We spend 3 days in this cute apartment. Good location, close to the restaurant area and the famous Sacre Cour is 2 minutes walking. Very well ventilated - 2 big windows - the place have everything for make you feels welcome. The bed is super conformable. No lift, but we don't mind the cardio moment on the stairs =)
We cook breakfast every morning with french delicious things from the store right in the front of the building. Lunch on different areas and dinner was on the Rue des Abbesses, so many good choices...
We meet Yann on our way out, very nice guy.
We highly recommend his flat for your stay in Paris.
