The location is perfect if you want to have the local experience of quaint little cafes, restaurants and bars of Vienna lanes. The apartment is near to all sorts of key locations, be it the museum quarter or subway station or city bike pick up points or even the shopping streets. We walked all over the city everyday and always had some great option for food and drinks at the local spots next to the apartment.
And the apartment courtyard is blissful on clear sky days :) Christiana was considerate with all the amenities and even basic coffee requirements.
The best part was a fan in the apartment since it gets too hot in August.
