Alexander and Bettina's apartment is superb! It is extremely spacious and was very clean and tidy for my recent visit. It's on the top floor of a nice apartment block with a quaint lift.
The whole time I was there I wasn't disturbed by any noise, so one can be sure of a relaxing night's sleep, ready for a day of exploring fantastic Vienna. It was also lovely and warm; very welcoming when returning from a day in the freezing temperatures.
The apartment is brilliantly located only 5-10 minutes stroll to Karlsplatz U, just past the magnificent Karlskirche. I walked everywhere except when I visited the magnificent Schonbrunn Palace, just 10-15 minutes away via U4.
Alexander and Bettina made me feel at home straightaway and are perfect hosts. When I return to Vienna, hopefully this summer, I won't hesitate to try to secure another stay.
