Katharina's apartment is in a great location, just next to the metro station, so Stephansplatz, which is the center of the centrum, is just 15 mins away! I stayed there with my parents, and as my mother cannot walk too much, it was really convenient! The house is simple, but great for travellers, you have everything you need: comfortable beds and kitchen with coffee & tea, good bathroom. Peter was a very helpful host, gave us all information we needed :) And as we came by car, the parking was right next door of apartment, so it was also convenient. All in all, if you look for a nice place to stay for a few days in Vienna, I can only recommend this apartment!:) Thank you, Peter&Katharina!
