I had great holidays in Vienna and Helmuth is a very friendly and courteous host. His place is well located (9. district, 15 min by walk or 5 min by subway to the city center). The appartment was clean and the bed was comfortable. Helmuth offered a little breakfast and gave some recommendations regarding sight-seeing and other activities. Those of you who forget to take a book with, may find something to read in Helmuths guest library.
