My son and I just recently styed in Paris for the first time at this Marriott RAive Gouche Hotel. The hotel was outstanding and the staff was wonderful. The hotel is well accessable via train from CDG airport, just a 5 minute walk from a station. They are also on one of the major train routes that takes you to all the wonderful sights in the city, Notra Dam, Eiffel Tower and the Arch.
Their Executive Lounge was outstanding, open from 0600-2400 serving breakfast, snacks, beverages and most evenigs wine. I highly recommend this location to anyone staying in Paris
