Mattieu is responsive and flexible. Efficient way of checking-in and checking-out (at least for young people as all done online).
Very quiet location at night which is amazing but at the same time many cafes and services around, and near-ish a metro stations (Rome and Pont Cardinet).
Bed was comfortable and good for a couple and the apartment size is also good "european/french" standards. And the most important, the building has an elevator (bugger than French standard) which is convenient for international travellers with luggage.
If I ever come back to Paris, I would stay there again.
