This apartment was just lovely! Check in was easy, and the host provided easy and clear instructions for us on how to arrive at the apartment, and met us promptly at the time we expected to arrive. He showed us around the apartment in detail and made sure the wifi worked before leaving as well. :) The apartment was spotlessly clean, very comfortable, and had all of the amenities we needed. It was very central to many tourist attractions in close walking distance, and also had an underground metro just a minute around the corner if you need to go much further. I would absolutely recommend a stay at this apartment if you are visiting Vienna, we hope to return sometime if we are so lucky! :)
