This is a great space and it is an amazing neighborhood of Paris. The food/restaurants were great. We were able to walk to the Eiffel Tower (a little more than a hour with young kids) and walk to many other key places (Louvre, Notre Dame) were closer.
The apartment itself is big, the kitchen is well stocked for cooking and larger families/groups have a nice big dining table.
The listing did mention there are stairs inside which makes the place not appropriate for the elderly or young children. It's also worth nothing there are 100 stairs up to the place. The first time up with suitcase was a bit of a surprise. After than it was a nice workout each day :-)
