Very comfortable, clean, and spacious apartment in the Augarten Park neighborhood. We were there for work in the neighborhood so it was very convenient. Very, very, close to a key tram that runs to the city center and a few minutes walk from Prater train/u station. It is not in the city center itself, but in a more residential part of town away from massive amounts of tourists. This does mean that getting to key sites requires public transport—which is very easy. A few minutes walk to great restaurants and bars, and with a supermarket right across the street.
