The apartment is really close to public transport and easy to reach from the airport, location is also great to explore the city centre. You can rent a city bike or mopeds just around the corner from the apartment.
It's spacious and really nice, internet works well and it's fast, the apartment was also very clean and tidy.
The bed is really comfortable and there's good space to keep clothes etc. The kitchen is quite big!
Downsides:
It's mid way between the first and second floor so bear in mind there's a few steps to do.
There's no extraction fan in the toilet and no windows.
Apart from that we had a lovely stay and we would definitely book it again if we come back to Vienna.
