Excellent location, and exceptionally cozy. Only a few minutes walk away from two metro stations and right down the street from the Eiffel Tower. Quiet, quaint neighborhood with easy access to groceries, pharmacies, cafes, and shopping; the keys themselves are accessed via a laundromat key box, so easy pickup and drop-off. There's also a small elevator in the building (!!), which is always a nice bonus.
I wasn't feeling especially sociable due to the timing of the trip, but Stephane and his family are congenial and welcoming if you have any questions. A good deal; I'd love to stay here again once I feel more confident about traveling overseas.
