Wat a lovely place and a lovely hostess. She answers quickly and is more than willing to give tips and trics about Vienna.
I loved the area, it is really close to the Donau where it is nice to walk around. I can imagine that in the summertime it is really nice to have picknicks and to swim.
If you are looking for a place outside the centre, I can recommend Elisabeth’s place. The public transport is very good in Vienna, before you know it you are in the center!
