All was as expected and we had a very comfortable time in Zoya’s apartment. The keylock system for check in/out is great as it allows for the necessary flexibility in case of unpredictable arrival/departure. Location is great with shops, restaurants, sights very close by.
Some things become a bit of a nuisance if you stay longer (we stayed 4 weeks), most notably the shower screen is not completely sealed resulting in significant leaks and mopping after every shower. Other than that, the apartment is all one needs for a comfortable short stay in Vienna.
