The apartment is very spacious and beautifully decorated. It has everything for a perfect stay in Vienna. The beds are comfortable, and the big rooms were great for a group of 6. It is very close to U4 metro station, which get you to Vienna center in 15-20 mins.
The check-in process was very easy due to informations provided by the host.
I totally recomand the apartment, a perfect choice to visit Vienna !
