This place is amazing. We had a group of 11 adults, and it was absolutely perfect. Great location, big rooms, nice kitchen, amazing bathrooms. We took full advantage of the sauna. The location a bit outside the city center but super easy with public transportation, and plenty of stores and restaurants close by. Bettina is the sweetest host, who greeted us, baked us a cake, got beer for us, and was super helpful and communicative. We could even buy additional beer from her for cheap which made it nice to not have to carry a lot of beer from the store. I can’t recommend this place enough for a big group in Vienna!!
