The apartment is very French and nicely decorated. It has everything you may need for your stay and Louis is a very pleasant person who is really to help you.
I liked the location a lot, you can walk easily to the main attractions (for a week stay I used metro only to get to the airport!), there are also several metro stations nearby. Personally 11th district of Paris is my favourite - it's full with grocery shops (that work on Sunday as well!), there is a nice market near the apartment and there are many very good restaurants and bars around that are not super touristic.
