I can't say enough good things about Deger's place. The apartment building is in a very central and convenient location, within 10 minutes walk of just about all the major attractions in the city. His building is very clean and organized, and his apartment is also immaculate. He made check-in very easy: he had pictures of how to find the building and apartment in the check-in instructions, then met me at the door and handed over the key as well as wifi, did a mini tour, etc. I especially appreciate that he allowed me to check-in early as I was meant to arrive at 8am but was very communicative and flexible when my train continued to be delayed for the majority of the morning.
The room itself is outfitted with everything you need, including still water, electrical cord, coffee maker, coffee pods and tea bags, and exercise equipment. There is a small desk and a very large, comfortable bed. The room itself is also very spacious. The bathroom was shared but was also very clean, and Deger offered use of his kitchen but I did not need it.
Honestly, Deger's apartment is high quality and great value, but the cherry on the cake is how much Deger cares for his guests, their stay, and their overall trip in Vienna. 10/10 would recommend to everyone!
