I booked Charle's place for one night for myself, my mom, 4 year old son and a baby. Our stay was borderline good/ OK. First the pros: Charles was extremely responsive so that is a big plus.
We walked from Gare du Nord with luggage and pram so that is totally doable.
Place is exactly as seen in photo.
2 good size and comfortable sofa beds in living room and one bed in the bedroom.
Had 2 fans in the living room so that was a plus.
I messed up on the check out time as I was running on UK time on my phone and Charles was very understanding and let us stay additional half hour
Cons:
Bedroom curtains did not block light - definitely should put blinds
Flat on 3rd floor with very small lift which can hardly accommodate one and a half person - had to pick up baby then fold pram ..also while checking out someone upstairs was moving home also and had blocked lift and hence my mom who can't walk many stairs had to walk down
In addition no shower gel or hand wash in main shower.
I think place great for anyone who doesn't have small kids or elderly folks
