Ingela has been the greatest host I have ever found on Airbnb, even if we never meet her! She gave us all the necessary information to get in the apartment per mail, and a lot of extra informations about transport or places to eat or to shop in Wien. The apartment was small but very clean and comfortable, because it had all the necessities, and it was 2 minutes away from the metro station: very convenient!
I strongly recommand Ingela's apartment! for those who want to stay for few days in Wien!
