This hotel is a total no- no in my list.
Is really difficult getting in contact with the hotel to try to figure out details. They do not have a "transfer service" as stated; the airport´s inter-terminal train will leave you naearby but is not the same (the main issue is that they don´t let you know this) when asked the answer was limited to "take the CDGVal" )without further indications) which as a tourist I had no clue what was that about. Staff was rather rude but the worst is the room itself: small yes but that´s the standard in France, bed was a rock, literal rock since it was a base with a 3 cm comforter as a mattress (NO mattress). huge gap in the middle of a twin bed, no working AC (turndown all around the hotel) but terrible hot inside.
It was a real nightmare trying to get any sleep.
Hotel is not cheap and there are tons of other hotels in the area, just do yourself a favor go somewhere else.
