I booked Wolf’s apartment for my parents, who visited Vienna in May. Wolf and his wife have been wonderful hosts. They greeted my parents personnally on their arrival and were very helpful with directions and touristic advice. My parents found Wolf’s apartment very comfortable and nicely decorated. Although they didn’t use the kitchen very much, it can help reducing your budget in Vienna and there is a grocery shop nearby.
The apartment’s location is central, which is perfect to walk and visit.
I would highly recommend staying at Wolf’s.
