What I would say first of all is that this location had two great characteristics: superhost and cleanliness. We felt very very well.
Good features: very clean, good location (bars, restaurants, public transport and bikes, park very close), had everything inside (dishwasher, clothing washing machine (new!) - for me traveling with small children is an important thing....); is way cheaper for a family or for two couples than similar accomodations/hotels.
Another very important thing:great perspective over Paris! My children loved it.
Bad features - could not find any to be so disturbing or to be mentioned here.
P.s. We travel a lot: 4 times per year at least and this was a very good place to stay. Recommend it!
