Armin's apartment is ideal in many ways - it is close to the Hauptbanhof, a few stops away from Karlsplatz and it is literally walking distance away from Schönbrunn. In fact you can walk to the center area in 30 minutes so if you enjoy casual strolls in beautiful Vienna, you don't even have to consider public transport! The apartment is just like it appears on the pictures, there is a large comfortable kitchen / dining / living room area with a bonus Roland electric piano at your disposal. I would recommend the place and I would surely return in the future!
