The apartment is very well located. Even though is not central it is 10 min from the heart of the city. Sladan is smart enough to provide free ticket to the parking lot (in the same building)! Austria Center is a few steps away and this makes the flat a perfect location in case you are visiting Vienna and attending any of the events (congresses and fairs).
Supermarket is in the same building (open from very early in the morning), as well as a small café and ATM.
