If you all want to be together, specify "4 persons in a 4 person couchette". I'm not sure if this train has adjoining double rooms, either economy or deluxe. CNL idicates they do. Deluxe has shower and toilet "en suite", Economy they are "down the hall". The reservation page indicates "4 persons in 2 economy (or deluxe) compartment" ie 2 separate compartments. You can get a room description at City Night Line pages at Deutsche Bahn.
