Quiet, right on the bike path, clean sanitary facilities. 15 euros includes water and chemical toilet discharge, there is no pit for gray water. The sign says it costs 1 euro and on the column you seem to have to enter a pin code, but just pressing the button is enough. You have to go up the stairs for the shower. Showers and changing rooms are a la gym. No privacy, but plenty of space. Hot water at the sinks is free. Nice manager.
