Nikolai's apartment has its own vibe and nice vintage furniture. The apartment is spacious and has extra cozy stuff like a fireplace, sound system, and guitar. We didn't use any of them but added something unique to the apartment.
The toilet does not have a sink which is not convenient but also classical in Austria. I even saw new apartments with the same - toilet without a sink. The kitchen is a bit dark and the metal sink is not perfect. Also, the shower is located in the Kitchen, and it is not comfortable to shower.
The location is really nice. Metro and Tram are near to the apartment. Mariahilfer Straße is also very close. Nikolai is replying quickly and Anni was really helpful about the check-in.
