I enjoyed staying with Isabel and Thierry very much! Can take a train all the way from CDG to about a half mile away! Their place is the perfect distance from the center of town: close enough to get to Notre Dame in 10min, and far enough away to get some peace and quiet. Can find anything you need very close by: restaurants, cafes, laundry, grocery stores, banks, and just around the corner from Mouffetard! They were very accommodating, polite, patient, and approachable.
