Last week I stayed with my 2 Adolescents girls at Belinda's apartment in Vienna.
It was great! Looks exactly as in the photo description here, clean, spacious, has AC.
Public transportation is 4 minutes walk (tram #62 takes you to all attractions in the city center), next to a bakery we got breakfast each morning.
Belinda gave us a warm welcome with her big smile :)
She was very responsive before and during our stay at the apartment. Our return flight was late in the evening, so with her kind heart, she let us checkout late in the day, which helped a lot with the luggage.
I would highly recommend staying at Belinda's!
