Tamara's studio is very well organized and in a good location as described on the Airbnb page.
The distance to the metro station was less than 5 minutes, so it was very convenient to move around the center of Vienna
(approximately 20min to StephansPlatz)
There are supermarkets such as SPAR and BILLA, and some restaurants around, so it was a good place to stay.
And, host's response to my request was very quick.
If I have a chance to visit Vienna in the future, I would like to stay again.
