The stay with Dominik was really nice, he had no problems with greeting us after midnight and on our leave day with keeping our backpacks till late evening. The flat was nice and clean, small room just enough for two people, multiple showers and toilets were really helpful as the apartment has quite a lot rooms and people staying there. The flat is near to public transport and it's in a strategic place between the city center and the Schönbrunn/ZOO complex, making it easy to get everywhere quickly. Really recommended!
