We had a great stay at Sigrid's place. It has very good transportation connectivity to all the places we wanted to go. There is a supermarket right across the street if you want to buy anything. 10 mins away there is an amusement park, WU (Vienna) Campus is like 15mins walk. The train station is just 5 mins away. Sigrid is punctual in replying to any communication. Overall, we had a good stay!
