We had a wonderful time at Marie's place, she was extremely helpful before the trip as well as during the trip, willing to come to the apartment at any hour of the night to accommodate for our lousy airline which got us delayed endlessly.
The apartment is perfectly located for visitors to Paris, within a 20-30 minute walking distance of the central locations and about 5 minute walk from the subway station.
There is a bakery and a supermarket on the street which made for perfect breakfasts.
Apartment has a fully stocked kitchen, washing machine, and even a piano!
Highly recommended!
