The apartment is very nice, furnished with taste, spacious enough, and it has everything that you might need.
But the highlight of the apartment is the VIEW which is simply amazing!
You can see the whole Vienna landscape from the balcony (and floor-to-ceiling windows).
The location is great and feels very safe. The building(s) dominate the area and are very easy to find.
The area is unusually quiet, even though it's close to the highway.
There is a supermarket and a restaurant just down the building.
Metro/tram station is 3 minutes away.
There are also two cheap outdoor parkings 100m away (6-10eur/day) as well as some expensive indoor ones (~45eur/day).
Highly recommended!
