This apartment worked perfectly for our family of 5 (kids aged 12, 10, 8). It is convenient to the Metro and to walk to many nearby sightseeing destinations, yet it is tucked away from the hustle and bustle of the city, so you come home to a very quiet street. Although the apartment is on the first floor and opens directly to the "street," that street is actually a pedestrian way with no cars and no major foot traffic, so it is both quiet and safe. We had plenty of room. We particularly appreciated the fact that there were air conditioners in the place (free-standing ones in each room), as it was over 90 degrees in Paris for our entire visit!
There are good Asian restaurants nearby - on a couple of nights, after we had walked around all day and had a typical French meal for lunch, we just wanted to come home and eat in our neighborhood. The Thai/Vietnamese place just down the street was delicious and there is a great cheap noodle place nearby (Happy Noodles) that reminded us of places in NYC.
Brooke was an incredibly responsive host, always responding to any question in minutes. She met us at the apartment to check in and was very helpful. I would not hesitate to book this apartment again; we really loved it.
