The studio is a very good choice to visit Vienna. It is close to the subway, and you can take it and arrive to the center of the city in a while.
Besides, it is a nice place. The studio was very cleaned when we arrived, and you have all you need for your holidays.
What I most value is the treatment received by Birgit and Walter, because they were waiting to us until midnight without any problem! They were very kind with us.
