My spouse, our son and I spent 3 nights at Jung Ae's place and really enjoyed it.
The location is great, 2 minutes walk from the metro stop (Philippe Auguste), close to many cafes and bistros, and it is a very safe area. There is an organic shop near the entrance of the building, as well as a bakery and two supermarkets close by: one about 40 meters from the apartment (Casino), and another one about 5-minutes walk from the apartment (Carefour Express). The apartment is on the 9th floor with a lift. The building is very clean and quiet, and so was the apartment. At our arrival, we collected the keys from the concierge, and we also left the keys with the concierge when we left. This self-check-in/out was very handy as it meant that there were no delays when we left the apartment. When we arrived at the apartment, we were happy to find a comprehensive booklet with instructions on how to use the router and to access the Internet, along with instructions on how to use the sofa-bed and a comprehensive list of good places to eat. I had to contact Jung ae to ask her about several minor questions (e.g., how to switch off the box temporarily, or where to take out the bin) and she always responded very promptly.
We were happy to see that Jung Ae used eco products for cleaning which means that while the place was very clean when we arrived, there wasn't a strong smell of chemicals. The main bed was very comfortable, and so was the sofa-bed in the seating room. We could hear some of the traffic at night, but we got used to it after the first night.
In addition, our son who is a toddler really enjoyed the place which was very safe for him because it was clutter-free, and offered a lot of space for him to walk around with no or very few obstacles on his way; in addition, there were many toys for him to play with, and he really enjoyed it.
All in all, this place was extremely suitable for families; it was clean, quiet, central, and especially safe for toddlers. We had an enjoyable stay and we would highly recommend this place.
