The space is great, very close to a metro station and easily accessible from CDG by rail. All of the flat is clean, from the bedroom to the common areas and restroom.
Check in was easy, as was checkout. Generally a pleasant experience.
Unfortunately, I never overcame my jet lag from the US, so most mornings I slept, and came in late as quiet as possible. Hopefully I didn't disturb too much. Vincent and his mates were quiet and respectful in the mornings as well.
All in all, a great experience and I'd come back again if looking to stay in the same area. Very highly recommended.
