The apartment is very comfortable and spacious and clean.
In the winter during the night in the sleeping area it is cold. But I think the owner could arrange to have an extra heater in that space.
Anyway Brigitte was very kind to us when we arrived there and both of them were responsive when I wrote them.
The space is located very close to the main objectives in Vienna, near to Stephan Platz. Which is great. You can visit a lot by walking.
Quite expansive but yeah...it's Vienna after all.
We enjoyed every minute there so the entire experience was great.
