Very nice from the outside. The whole architecture by Hundertwasser is just amazing. It's a must see if you are in Vienna. You gotta pay for going inside. But in my opinion the more important part is the outside facade which you don't have to pay for to see it. Sadly on the other side of the street there are constructions going on. So it's difficult to get a great shot.
