Gundula was easily one of the best housing hosts I've ever had, Airbnb or not! Her place is absolutely fantastic as it is very very cosy with awesome art work, had nice amenities for a morning meal and is easily connected to the rest of Vienna. There are two train stations that make every big destination accessible within 30 minutes, including the airport. Gundula herself was also very very warm and welcoming, greeting us herself and making us feel right at home.
I would absolutely stay here again for another trip to Vienna. Gundula's place and her warm hospitality made my first stay in Vienna even more special :)
