We were more than happy with our stay in the Appartment. Due to some unfortunate events, we needed a place to stay at very short notice. Afgan made it possible for us to check-in just a couple of hours after we booked. He was very nice, even brought as some drinks for check-in and quickly replied to a couple of questions we had.
The apartment itself is located within walking distance from the U1 and U2 line and was perfectly clean and equipped.
I can fully recommend this place if you're planning to stay a couple of days in Vienna.
