The apartment is really close to the Innere Stadt, the historical heart of Vienna. It takes only approximately 15 minutes using the Wiener Linen to get to the Volkstheater and the Ring.
The flat was truly clean and there was everything you may need during stay there. In case you need help with something you can count on hosts' quick response via Airbnb app. Their hospitality and eagerness to help was really extraordinary.
I strongly recommend this apartment and the hosts.
