I can't speak more highly of my stay in Marie's apartment. The location was superb--just adjacent to the Place Cambronne, with a solid boulangerie and restaurants, and not far from the Eiffel Tower. I visited the Champs de Mars every day to run, as Marie suggested. The apartment itself has everything a seasoned traveler need for a short stay in Paris: wifi, hotplate, fridge, decent-sized bathroom, and a nice view of the city. When I first arrived, Marie was kind enough to invite me into her apartment for some local tips and an espresso, and she was always responsive questions. I highly recommend.
