Véronique & Olivier are among the best hosts I have met. First of all, they are very flexible, amazingly nice & with great discussion. I came around midnight but it was not a problem getting the key. They are of great personality and have a lot to share regarding history, culture, languages & many more aspects of Vienna.
Secondly, the room is very quite with private bathroom and your freedom is kept as you like. The breakfast was very nice & served on a nice rooftop terrace when sunny enough. I could borrow umbrella & hat on suitable occasions as i had forgotten to bring mine. Finally, the location is amazing as a few minutes walk to the city center.
I would recommend Véronique & Olivier 100%. You would not be disappointed.
