Public toilet paradise by haiamisa
Vienna has more public toilets than any other place I have visited. There are toilets everywhere! You never need to worry, every street, every main crossroads, every square, every U-bahn station has a nice clean public toilet! It costs some coins, 40 cents if I remember right ( keep change with you).
You can even plan your toilets trip online with this Vienna city toilet site. Click on the area you want (district number) then on a toilet name and you get a map showing where it is!
Many places in the world should learn the Viennese way!When the need is big the help is near!
