Bertrand was FABULOUS at communication(s) before and during our stay. The subway station is about a 10 minute walk and there are plenty of places to eat around the neighborhood. Although, it's easy to get around on the subway, the attractions are about half hour on the subway (at least). I felt it was easier to take a taxi or Marcel to/from Airport but getting around the city on the subway was a lot easier than renting a car. Walking to/from subway if you have heavy luggage or several luggage would not be easy.
A quick note, although the flat is SUPER cute, there are stairs that go to the basement bathroom that are pretty steep, so if you have any issues going up / down stairs, please keep that in mind.
I would recommend Paris Champion!! :)
