One of the great sights of Vienna was this part of the city called Hundertwasser. it was quite easy to access through U-bahn and walking. A great date spot!
It's not a lot but enough to be amazed! I'm not sure if I'd like to live here, I mean there are tourists there all the time. Or maybe you get used to it...or not?!
Anyway, if going to Vienna, pay this small area a visit!!
