Helmuth's appartement is very well located in Vienna, close to the subway of close to supermarkets, pharmacy and so on. The bedroom is very comfortable but one thing maybe: the curtains were very transparent but it wasn't a problem for me because I got up very early during my stay. Helmuth is very kind and gave me a lot of advices, where to go in the city, which restaurants and bar to enjoy with some friends. I thank him very much for his attention and I will surely contact him if I go back to Vienna in the future.
