Chris is an exceptional host and friendly and discrete. His house is perfect and even better than the listing photos. Very clean, warm and well maintained and well equipped. He also had a laptop in the guest room available. I really enjoyed that it was only a few steps away from underground line 1 (red line). Great experience for the first time using Airbnb. I would highly recommend Christian, and if I ever visit Vienna again, Christian's house would be my first choice.
