Very nice apartment, much better than the pictures.
It was very clean, located in a new (or at least new-looking) building.
Good amenities especially if you are interested in cooking there, great internet connection (fibre), and great communication with Irene!
The location itself was a bit outside the city centre (Floridsdorf) but it's easily accessible with either the S trains or the U6 metro line.
100% recommended!
