You mentioned car service. What did you mean? Is there car service from the airport?
I did not mention car service - sorry. However, I'd recommend using Uber in Paris.
Sorry, maybe that was another review. I didn't mention car service in mine. This hotel has no shuttle service, however, the metro is only about 200 meters away. Our friends used a taxi to go to the airport for their morning flight. As far as I know, only the hotels out by CDG and a few high-end hotels have shuttle service.
