Vienna Public Toilets in the Center

Where can I find a public toilet in the center of Vienna? In the city-walks map many public toilets are marked with a "WC" symbol. Additionally you can find some public toilets in most of the metro stations in the inner city of Vienna.

You have to pay in the most cases approx. 0,50 Euro for the use. Unfortunately the opening hours are not standardized, but most of the toilets are open during the day between 9:00 and 18:00 o'clock. In some metro stations in the center of Vienna the public toilets have usually longer opening hours.
