We had a wonderful time in Vienna. Carina and Georg's apartment was the perfect base for our holiday being round the corner from the U-Bahn station Schlachthausgasse, it's only a short distance from the main squares Stephansplatz and Karlsplatz. The u bahn was the easiest way for us to get around and see everything we wanted to see.
The apartment itself was very clean, very spacious and incredibly well stocked (they think of everything). And after an exhausting day sightseeing and touristing, it was a perfectly cosy place to come back to in the evening. And the beds, UNREAL! So comfortable, we never could get up in the morning. If we come back to Vienna, this apartment would be top of my list.
