I spent a short time in vienna with my friend and we really enjoyed this two days. Katharina and Peter's apartment is beautiful and clean. I loved the bed! It's very comfortable! The location is perfect, the westbahnhof is near from the apartment, where you can use the public transports. Katharina and Peter were very friendly and helpfull. In the apartmen were some maps, that was a big help for us. If I go to Vienna the next time, of course I will choose this apartment again!
