The location and balcony are lovely to enjoy Paris. The balcony in particular had sun in the morning but by mid-afternoon on it was in the shade which made sitting out on it gorgeous to enjoy the outdoor time in the summer. We often ate dinner or read a book outside. Close by to a little mini-mart as well as a bakery downstairs for morning pastries. The area is very pedestrian friendly with lots of restaurants - the bars can get a little louder on the weekends, but the windows are quite good. Very central to everything you want to walk to - the Bastille is in one direction and Eiffel Tower in the other with the Louvre fairly nearby.
The apartment is definitely large for Paris standards and well laid out for us and our two kids. She lives there part of the year and you can tell that she's figured out all the little things to be comfortable like upgraded power outlets, integrated USB charger near the bed, bathroom and kitchen supplies, etc. Good communication as well.
