Jan and Maida are great hosts. They are kind, accommodating, friendly and very warm people. They waited late at night to check me in and were very helpful in guiding me about the city. The apartment is perfectly located in the centre of Vienna with great connections to almost every corner, including the airport and the main train station.
I highly recommend the great studio, it is artistically done and is still very functional. I had a great stay here and would love to come back.
