Sarah & Markus were A++ host.
Communication was smooth and fast, check in , check out also.
The place was sparkling clean, very quiet at night and during the day also, so plenty of rest.
Easy access to the public transportation, they have a nice parking space and Markus was very quick to show me how to operate it.
They put a lot a lot of effort in making sure that you have everything you need and you can feel home away from home.
Bottom line,
If you are visiting the beautiful Vienna,
You will make a vise decision by choosing Sarah and Markus as your host.
