I had a nice time at the apartment of Konstantin. It is situated at a very nice quiet green residential area of Vienna. From the window I had a small view of the garden. It was clean and Konstantin was very quick to respond to my questions and always very polite. The bus to get to the city center stops right outside the building. At night it is very quiet someone can really sleep very well. The room had everything needed for cooking and I really appreciated the welcome gift the chocolate cookies. Thanks!
