65€(!) – and that's just the starting price – for quick shower sounds pretty steep IMO. And I wonder who, during a stopover, is even interested in to travel from airport to city and then back to the airport for such a few hours. Is that even possible at CDG, for example? Many airport and lounges also have showers these days. If you live in the city, you probably take shower at home and if you are staying for longer time there you anyway book a room. So, to whom is this targeted?
