Location, location, location!!!!
You won’t find a better located place for a few days to get the best out of Vienna.
Shops, bars, restaurants and sightseeing are all on the door, along with fully connected transport links, just outside.
The apartment was very clean and had everything we needed. The pool table was a big bonus and kept our 10 y o very happy (well except when he continued losing to me!). Spar around the corner is good for supplies if you want to cook or just have breakfast in. The Nespresso machine helped with this, too.
When we come back to Vienna, we hope we can find a time when we can stay again.
