The apartment is perfectly situated, you can grab scooters/trams or buses to explore the further reaches of Vienna or simply walk 5mins back across the bridge and head downtown.
The apartment was clean, everything worked, and was exactly as it was advertised it would be - our hosts went above and beyond to accommodate us (we had a late flight and they let us store our bags, and we arrived early and also let us store our bags so we could explore unencumbered!
Thank you! I would stay again and would recommend to anyone looking for a bolt hole in Vienna.
