Let's start with positive points. The apartment itself is very clean and well equipped. Public transport access is perfect. Lots of grocery shops, restaurants in 1 or 2 minute walking distance. Check in/Check out was super easy.
The negative points for us include: being at the 5th floor and no elevator, specially if you have an old or physically disabled person in your group this apartment is a no go for you. Even for us it was a big hassle to get our baggage up and down considering almost 100 stairs. Also there are almost 10 stairs inside the apartment to get to 2 bedrooms and the bathroom.
Another point which I'm not sure if it counts as negative or positive is that, it is in the Indian district of Paris. It is Ok, I myself like Indians. But as you traveled to Paris and not Mumbai it is somehow too much. So don't expect to see non Indians in at least 1 kilometer distance from the apartment. It does not fully feel like you are in the heart of Europe.
