We had a great stay at Helene and Rainer's place. Nice and very clean apartment with absolutely everything you need ! It is well located near a train station, an Ubahn and 'city bike's station. You can also walk to the beautiful Schönbrunn palace. Rainer and Helene are extremely nice and gave us many tips for our weekend in Vienna. I definitely recommend this Airbnb and wouldn't hesitate staying there again.
