This apartment has excellent access to the RER. So if you need to catch the train to the CDG airport, this is an excellent solution; however, we felt that the worn state of the apartment and less that sterling cleanliness made this an overpriced stay. We were particularly unhappy about the leak in the ceiling. A water leak had caused extensive water damage to the ceiling and wall. The temporary solution was to stuff a towel in the hole in the ceiling, but we heard the water dripping alarmingly close to our heads all night. We were not warned about this beforehand, nor were we given a discount for the inconvenience.
