Dieter was a terrific host and helped to orient us to Vienna. The apartment is beautiful and exactly as advertised. Spacious, clean, bright and airy flat with excellent wifi connection. The bottle of wine, espresso coffee pods and milk in the fridge were much appreciated touches as we arrived in a new city. As he said, the public transport system is top-notch and we had no trouble navigating, with a "U" station just around the corner from the apartment and over the bridge. Very easy. We loved every minute of our two-night stay and only wish we could've stayed longer.
