I arrived in Vienna a few hours ago and will probably have a free day tomorrow, any recommendations to what I should visit here? :D
schloß schönbrunn would be my 1st choice, then the stepahnsdom and all the old city, also the hundertwasserhaus is really nice to see if you have some more time, dunno how fast you are visiting stuff, and if you are into museums, i highly recommend you the albertina!
if you are also free tuesday night we can drink a beer together :D
