This is a wonderful apartment that gives you all of the modern elegant minimalism of Europe in the middle of District 1 Vienna: scenic, historic architecture in every direction. Epic just walking out the front door!
Osman was very communicative and flexible around handing off the key when our plane was delayed by almost 4 hours. We were grateful he was so understanding!
There are several extra touches to make your stay a pleasant one, including a washing machine (and drying rack) and a Nespresso machine in the kitchen.
Also there's a very nice atrium that gives the apartment quite a lot of light.
Can't say enough about the neighborhood, you're right in the middle of everything.
Couple things you might consider bringing:
1) A tiny night light. Between the bedroom and bathroom is a film-covered glass wall that slides open. So you might want a little extra light to navigate that in the middle of the night.
2) Modest pajamas if you're shy. On your way to the bathroom in the apartment, you'll pass large windows that could be seen by the neighbors.
All in all, we'd strongly recommend the place and enjoyed our time there.
