This was one of the best airbnb we ever stayed at. We went to Vienna for three nights and lived three persons in the apartment. The apartment is placed in the best area of Vienna, many restaurants, shops and bars just around the corner.
The apartment had two (!!) amazing balconies, high sealing that made it very bright, beautiful furnitures, good music device, beautiful bathroom and shower, and amazing kitchen area. We had everything we could possibly ask for.
Gerhard was a extremely good host, he responded very quickly at email, answered all the questions, gave us some tips on really good restaurants.
We couldn't ask for more. I would definitely stay here again if I'm going back to Vienna.
