Martin's apartment is small, clean and cozy and it's located conveniently close to the U3 subway station, Hofer (Aldi) supermarket and the beautiful Shonbrunn Palace. It had everything we needed, kettle, coffee machine, a nice shower, and a comfortable bed. Heating works perfectly and the apartment was never too hot or too cold. Communication with Martin was a bit slow, but everything was so straightforward that we had no hassles. We'd definitely stay there again whenever we're back in Vienna.
