This is a beautiful, airy, sunny altbau apartment. It had everything I needed for cooking and working, and was an ideal base for exploring Vienna (I got to the Ringstraße within around 15 minutes by foot). There are great cafes and bars nearby, and the UBahn is right on the doorstep to reach the historical city centre conveniently if you don’t feel like walking, as well as for easy access to the airport. Highly recommend. Check in process was also very easy.
