The apartment is very well located only a couple of blocks from the Ecole Militaire and the Eiffel Tower. It is just steps from a large subway station that has 3 lines passing through it. There are nice restaurants and shops right out the front door. The apartment itself is quite spacious with two independent bedrooms and a living-room separated by a small corridor.
Anne-Marie and her husband were very welcoming in receiving us. She even went out to the metro station to fetch us. They showed us the place and explained in detail how to work all the appliances making us feel very welcome. They also let us check out very late on the day of our departure.
I definitely recommend contacting Anne-Marie if you intend to stay in Paris.
