i've visited vienna twice now. once in november, once in june. vienna is a vibrant, gorgeous and exciting city. the arts, culture, everything is fantastic, and the people are friendly and charming. one of my favorite museums - the belvedere - is there, and the gardens near that are also gorgeous.
i can't wait to go back to visit. i would say go in the summer, the winter (at least the week i was there) was dreary. i also love the cold war history of vienna, so that was exciting.
thanks for sharing.
