The apartment is as described, not small, not enormous but spacious enough, well furnished and clean.
It's very close to the metro and the tram, and the area around it is very quiet and safe.
Dominique is a very kind and caring host, he was careful in describing eveything needed in details and gave us good directions.
I would totally recommend this place, especially if you're looking to attend events at La Grand Halle de la Villette.
