I had a great stay at Dominiks place!
Even though I had difficulties with my arrival time Dominik was super flexible and waited for me at the flat.
The flat and the room was nice and clean.
It had a kind of youth hostel atmosphere, just that you have actually your own room :)
For Vienna the price was really cheap and the surrounding was fine and very easy to get to the center via Metro.
I can recommend this place! :)
