We really loved this apartment. It’s spacious, generally quiet (occasional sounds from the school next door and the métro but really not bad), and the laundry facilities are a great help. It is a ground floor flat and there are skylight windows that provide plenty of light, but, unfortunately, no fresh air. We stayed in early September when it was unusually warm and the AC worked perfectly.
The 15e is a wonderful neighborhood, part of the true Paris away from the tourist areas. Access is s great via the 12 (very close) and the 8 (not too far away) métro lines, the tram (about a 10 minute walk), and several bus lines. There are lots of restaurants to choose from of various ethnic choices (including French), as well as traiteurs, boulangeries/pâtisseries, markets, and lots of other shops. But, we used to live in Paris, have visited many times since, and know it pretty well, so staying in the 15e is, in a way, a way to explore something new. It’s a bit out of the way for museums and other tourist spots, so if this is your first time in Paris, it might not be ideal — but if you’re looking for something different, this could be a great choice. We would definitely stay here again.
