This is a nice apartment! It is small but there was enough space for 2 adults and 2 kids. It's on a fourth floor no elevator, this may be a problem if you have any mobility problems but it was fine for us. Stairs are narrow it was difficult to bring a stroller upstairs everyday, we left it on the first floor after a couple of days.
Location is perfect, close to everything.
We enjoyed our stay and our trip to Paris, would stay in the Delacroix apartment again!
