The apartment is located well. There are lots of shops around, including grocery stores. The metro is only 5 minutes away. The Eiffel Tower a 15 minute walk.
The apartment is very spacious. We were traveling with kids (10 and 6) and they were easily entertained by the toys and games in the apartment. The furniture is old, just like the building, but the beds were comfy.
Marie was very quick in her response to my emails and accommodated us well (we were able to leave our luggage in the apartment a bit longer on departure day)
