MaryAnn, I've used them before from the Hotel Leveque; they were extremely reliable. The driver came looking for me in the lobby, since he was parked on the corner because he couldn't get to the front door because of pedestrian traffic. It took one hour to get to Charles de Gaulle during rush hour. However, they insisted on picking me up at 5 pm for an 8 pm flight, which was then delayed two hours. Maybe they didn't have enough passengers for another trip to the airport. They use VW minibuses, very comfortable, and the drivers are really good drivers and speak good English. I also did a day trip with them.
