We had a four night stay in Katharina and Peter's apartment and thoroughly enjoyed our time there. The facilities in the in apartment were excellent and exactly as cescribed. We appreciated being able to use the washing machine on our arrival as we had been on the move for a week or so.
Communication prior to our arrival was very good and Peter was at the apartment to greet us on our arrival. He explained everything we needed to know and took the time to give us useful tips about restaurants etc.
The location of the apartment, near the trams and trains at Westbahnhof and at the top of Mariahilferstrasse, is ideal for easy access to the sights of Vienna.
