We enjoyed our stay at Evelina's apartment very much--a main tram line (#2) stops right outside, the U6 is just down the street, and the Ringstraße is an easy ~20 minute walk. Evelina was pleasant and the location is away from the throngs of tourists--very safe and cozy. It is quite clean, stylishly furnished, and close to cafes, shops, and grocery stores. I would stay at Evelina's apartment again--it enabled a wonderful trip to Vienna.
