This was my best Air BNB experience ever!
The apartment is spotless, well appointed, and is exactly how it appears in the photos. It is a great location- centrally located and very close to public transport.
Walter was out of town so our contact was Thomas. He was so incredibly helpful- everything from suggestions for what to see in the city to printing out train tickets- at 11:30 at night from his own home printer.
If you are coming to Vienna, look no further: this is the place you want to stay
