Stavroula & Klaus are very friendly and attentive hosts. I stayed at their apartment with my boufriend and they took care of every possible detail and made our stay in Vienna really enjoyable. They gave us good advice on what to visit in the city and where to eat for a good price, let us do the laundry and gave us a veru good map of the city. The kitchen and the room were really spacious and clean. We definitely recommend staying with them.
