The apartment is perfect! The place is nice and clean, exactly as described, and in a nice neighborhood. There is a small market place nearby, and a nice larger store with all the basics. Most of all, there is a bus station basically across the street, which connects you to the awesome and quick Vienna public transportation network.
Anastasia wasn't in the city at the time of our staying, but she did all the preparations and forwarded us the key perfectly. All in all, I am very happy with the whole arrangement, and Anastasia's hospitality.
I absolutely recommend this apartment, and hope to return to this place again soon.
