The place is easy to find, well located and very close to all main Vienna attractions. I didn't have to use any public transport - I could walk everywhere.
Just around a corner there are few cute cobbled streets with probably best restaurants in town.
The flat itselt is huge, really spacious. Well decorated, clean and comfortable. Large bed :)
I enjoyed my stay and would choose the same place if I come to Vienna again.
Thank you Amndrei!
