This apartment might look nice on the photos, but it stinks with the cigarette smoke and toilet fumes. There is clearly some problem with ventilation, as all the ventilation from the kitchen, toilet and shower is closed off (in toilet with a masking tape), and as a result, all the smells remain in the apartment.
Everything smells as if the apartment was previously inhabited by heavy cigarette smokers, and little has been done to solve this before turning it into the airbnb property.
There is a reason the kitchen isn't in the photos - it is very dark, smelly and crowded. Dish towel and cleaning rag is missing, we had to use our towel to dry the cookware.
Plus, the apartment was cold, and it took a long communication with the owner to actually turn on the heating.
I usually leave very positive reviews, but this experience spoiled our entire trip to Wien. Avoid.
