No issue on the stay. The apartment is as what the host described on the listing. We did walk up flight of stairs everyday to get to the unit so I would consider this second floor.
We spent quite some times to commute between this place and major landmarks near city center or west side around Eiffel tower. For family with tight timeline, I would opt for staying further west than this location.
With family of four and opening up the sofa bed, there is not much room left in the apartment to move around. Overall, the host is experienced and delivered what is listed.
