My friends and I had a fantastic stay in Vienna. Because she was unable to be there herself Anna arranged for her mother-in-law to meet us outside the apartment when we arrived and she kindly helped us to settle in. The apartment was perfect for the 4 of us - very centrally located, close to the underground lines 1 and 4, and within walking distance of many excellent restaurants and bars. Can highly recommend Anna's apartment if you are planning a trip to Vienna.
