I stayed at Anna's apartment for 3 days and felt at home. Lena and Anna were friendly and helpful.
The apartment is situated close to the city centre and metro station. The check-in was easy. Anna's sister Lena met me and showed the apartment. She also provided me with some useful info about Vienna.
Anna's apartment is cozy and clean. The water heater and the Wi-Fi work well.
I had a great time and would highly recommend this apartment!
