It was actually my first time in Vienna and I stayed with 2 friends for 3 days in Werner's apartment.
The accomodation is quiet well located - few minutes far from the subway U1 and not so far from the Hauptbahnhof.
The apartment was very clean and of good size for 3 people. And everything was there.
Werner was a super nice host (and I'm sure he's still 😄). He gave us precise information on how to get to the apartment. And the arrival and departure process were super clear as well. Werner was also very flexible on the hours which was super nice.
Overall, I'm sure it helped, to have such a precise, easy reachable and friendly person as host, to enjoy our stay in Vienna.
