We had an excellent stay here. The location is amazing. In the evenings we walked with our kids a few blocks to Square du Trocadéro and enjoyed the beautiful view of the Eiffel Tower (and the energy of the crowd). The metro station is also just a few minutes' walk, which was super helpful in getting around. Some other little nice things about the location: there are a supermarket and a bakery right across the street.
As to the apartment itself, the cleanliness and working amenities were a relief (after a stay at a different and less satisfying place built in the same era). It was easy to get a fresh cross-breeze on the hotter evenings, and one of the bedrooms was on a quiet courtyard (as quiet as can be within the city). We heard no noise from neighbors.
We'd definitely recommend this apartment for a stay in Paris.
