My overall feedback is very positive.
Location is great (1min walking distance from Centre Pompidou and close to the metro/trains station Les Halles), the apartment is quite small but very comfortable and clean. You find all you need.
Patrice was a perfect host-we could not manage to meet but anyway he gave me all the information and the support I needed during my stay.
He was also very flexible with the check in/out time.
Perfect solution for weekend in Paris.
