We stayed at Djamel's place for 5 nights with our family of 2 young children. First want to comment on the location of the apartment. Depending on how you want to experience Paris, this may be a positive or negative. The apartment is far removed from basically all tourist sites such as the Louvre museum, Eiffel Tower, Arc de Trioumph, etc. You're looking at 20-45 min on the metro to get anywhere. Traffic is so bad in Paris that it's often faster to take the metro than take an uber/taxi. However, the neighborhood feels much more like a local neighborhood with a lot of good restaurants away from tourists. The bakery right across from the apt is very popular with locals lining up everyday.
The biggest issue we had was the mattress in the main bedroom needs to be replaced asap. Could not get a good sleep because how uncomfortable it was. Bathroom was also VERY small. Other than that, we enjoyed that it was a corner unit with a lot of windows and it was very clean.
