Conception of a rest room in very long range aircrafts
 

I'm working on a study about organizing the rest rooms on board for pilots in the case of very long range aicrafts like the future A3XX. I would like to have your opinions, suggestions on what would you think necessary in this type of rest rooms. All kinds of information you would like to say about the comfort, the space you request to have a good and rapid rest, all sorts of things you have in mind and things you need. It would help this study and make a big progress, taking the request of pilots to create things for them. An online sample survey to make human factor in aeronautics progress.
Thanks for your help
