Marie's apartment is beautifully decorated, cozy, and clean. Marie was easy to contact, and the key pickup went smoothly. The location is wonderful, with easy Metro access. The apartment is also walkable to the popular Du Pain et des Idees patisserie! I would definitely stay here again.
If you're American, don't forget that the ground floor is considered "floor zero", and that the second floor, where the apartment is, is up two flights of stairs (not one flight, like where the second floor would be in the States) :-)
