I looked for the apartment near AKN clinic, and Georg's apartment appeared in two minutes of walking from clinic and one minute from the subway that is incredibly easy to use. The small two-room apartment almost in the most historical center (5 minutes by car or 2 metro stations) in the old house with the very tall ceilings, all necessary, except TV, is + the hospitable and pleasant owner :) I remained is happy to compliance of the price and quality. I will leave this apartment on a note for the following trips to Vienna.
