We didn't see Johannes but the communication by phone and email was accurate and clear. The apartment is spacious, modern and super clean. Well equipped kitchen also. It is situated in a quiet neighborhood, almost in the center of Vienna. From the apartment it is 500 meters walking to the first metro station and from there you are in 10 minutes in the hart of Vienna. A good thing also is that we found always place nearby the apartment to park our car. The wifi wasn't working but we not came to Vienna to surf on the internet, so this was no issue for us. For us a perfect place to visit Vienna. Thank you Johannes!
