We've stayed at many wonderful places through Airbnb, but this may have been the best in terms of central location, cleanlinest, ample space, communication, and check in/out. My family's time in Vienna was truly spectacular, and so much of that was because of where we stayed. If you've never been to Vienna, the apartment overlooks Graben (a historic central street and plaza which is only for pedestrians). We could practically touch St. Stephan's cathedral. Our windows overlooked the famous Column of the Trinity. On most evenings, individual opera singers and classical musicians would have street performances right below our apartment and it seemed as if they were serenading us. Absolutely magical. It's a wonder that such an apartment is available on Airbnb. Our hosts, Ludwig and his father Andreas, could not have been any more accommodating or helpful to make sure our stay was perfect.
