Susanne's place is perfect to explore Vienna from. Its central location near the underground and supermarkets is great. Besides taking the underground we also walked to or from the inner city or to the Donau island a few times. The apartment was very clean and stylish with an awesome old wooden floor. Well equipped kitchen and modern bathroom. The beds have firm but comfortable mattresses. The road in front of the building has a lot of traffic, because of (young) people visiting the nearby permanent fair. It didn't bother us, but it's good to be aware that you can experience some city noise. We didn't meet Susanne, but her friend Thomas waited for us outside and was very friendly and helpful and took his time to explain the city and the main attractions and shared some local knowledge with us. Highly recommended
