Doris´s place is wonderful! We had the whole flat for ourselves: a well equipped kitchen, comfortable beds, a clean bathroom. The location is perfect: not far from the main train station and metro U2 station, walkable distance from the city center. The neibourghood is super safe. We felt very good there.
Last but not least: Doris is a great and a very friendly person. The communication with her was just perfect.
Overall, we enjoyed our stay in Vienna very much.
