Alexander’s place is truly wonderful, perhaps the best Airbnb I have had the pleasure of staying in.
I spent around 2.5 months over the summer in the place and I enjoyed every moment. The apartment was very clean, well equipped and perfectly placed in Vienna. With only 5 minutes by foot you reach a U-Bahn station and in 10 minutes you are in the city centre (not to mention all the other transport options available). The apartment is comfortable and cozy. As well, communication with the host was fast and efficient.
I can not recommend this place enough, for either a short or long term stay.
