My husband and I were staying here last weekend. The app is perfect situated-20mins walk to the main square, 3 mins to the Sbahn, 3 mins to the supermarket. Just in front of the app is a small and cosy bar. Our flat was fine and clear. The app has 2 or more room and can be suitable for big companies and couples. But if couples and noisy companies after Oktoberfest or other fest meets at the same time, it can be not very comfortable to share bathroom ;)
Konstantin was very nice with us. After the leaving the flatmates he made in order everything and clean common places.
