What a wonderful place! Simply put, I know exactly where I want to stay every time I return to Vienna. The apartment was gorgeous, spacious, exactly as advertised, and nothing more than a short walk to the Stadtpark U-bahn stop or City Center. It was extremely easy to communicate with Caroline and Martin, and their comprehensive "Vienna Guide" email was very helpful for arranging transport to the airport, to decide which Konditorei we'd visit that afternoon, and which wine bar we would frequent after dinner. They are the ideal airbnb hosts.
