My maternal grandparents lived in Vienna. I visited them there a number of times when I was still of school age (before anyone says it, yes, a lot longer than 10 years ago) and loved it. They had an apartment in a real old-fashioned building with a creaky old lift like something out of Hitchcock, you went everywhere by tram which I found quite exotic, the food was cracking - fresh bread rolls from the baker at sparrowfart every morning, AMAZING cream cakes and ice cream shops, sausages of every conceivable kind - and of course I loved the musical side including the opera. Ought to go back and take another look sometime.
