It was a great experience! Lena came over and gave us the apartment key just when we got to the airport. She helped us with everything (the Wi-Fi working, directions to get there…). The apartment was very clean, the bed was big and comfortable and there were two electric heaters that kept us warm in this freezing winter season. It was very close to the underground station Praterstern (U1), which takes you to the city center very quickly (only 3 stops). I would totally recommend this stay!
