I spent the first few days of my arrival in Vienna in this nice apartment. The flexibility of Werner's offer was appreciated as I arrived directly from the airport. It is also quite easy to reach by public transport.
The apartment is simply excellent. Everything is new and clean. You will be able to get a good coffee/tea in the morning and the kitchen has all the essentiels you need to prepare your meal if you feel like it. Otherwise, you will find the basics services nearby (grocery / take-away restaurant). The bathroom, like the rest of the apartment, is very clean and functional.
I spent most of my stay without the second bedroom being occupied. This gave me even more privacy.
The bedrooms being each one on a different side of the apartment, the intimacy is therefore well preserved and gives the opportunity to share with the other residents in the common areas.
I recommend :)
