I stayed at Isabelle and Michel for a week and I had the best experience I could imagine. Isabelle wasn't there, so I didn't have the chance to meet her - but Michel is more than just a host, he is a friend. The room is cozy and warm and the whole house is super cute. The location is also not bad, it takes nearly a half an hour walk to get to the center, but the metro station is very close and the neighborhood is a quiet one.
