This apartment is an excellent choice, especially if you look to spend more days in the Schönbrunn area.
Walking distance to everything that's in the Schönbrunn park (Zoo, the palace, gardens, public pool). Also walking distance to Wien Technical museum and U4 (metro to city center).
4 different supermarkets in the area. Over 10 restaurants and terraces. Also, 2 streets away from a petrol station (note that on Sundays, the supermarkets are closed, petrol stations being the only place where you can buy some stuff).
The apartment is on the ground floor, making it also suitable for the families with small children. The neighborhood is very chill and quiet. At the time of our stay (June 2019) the apartment was less than 1 year listed so, obviously, everything inside was in perfect condition.
Also, worth mentioning that Adrian took some stress out of our shoulders and helped us with the transfers.
