I had a really good stay in Vienna at the apartment of Astrid which is super nice and in a wonderful position close to the very city center. The room is clean and cosy and everything is comfortable at the apartment. You feel like at home. Astrid is always available, very polite and at the same time an interesting person to talk with: she can give you good advises about the city. I will be back next time I that I will go to Vienna.
