Dominic greeted my wife and I at the flat. He gave us a thorough tour of the flat, and then we looked at a map of Vienna and he explained a few key things that were very helpful for our visit. The flat was great; very clean, comfortable bed, and the espresso/cappuccino machine was excellent. Dominic had filled the beans in the machine before we arrived and I think we used it every morning. Dominic was very reachable with WhatsApp, and he offered us suggestions for different restaurants in the area based on our preferences. We really enjoyed our visit to Vienna, and would definitely recommend staying at Dominic and Birgit's flat when you're there.
