Katerina's apartment is spacious and very nicely furnished to have everything you'll need for your stay. My husband and I stayed for 4 nights. The subway is very close to the apartment and only a few stops away from central Munich. There are grocery stores, restaurants, coffee shops and anything you'll need within walking distance. It is a ground level apartment but up a bit from the street. During the day and evening there is a little bit of ground traffic but it is quiet at night and we never had any issue. We would highly recommend if you're looking for a comfortable and central stay in Vienna!
