Klaus was just great. I enjoyed my stay and I think it’s a perfect place if you travel alone and spend in Vienna a couple of days. Very quiet also at night, safe and nice neighbour.
The only (a bit) uncomfortable thing for me was the wood floor in the aisle, that creaks very much, as well as the door of my room, and every time I had to go to the bathroom at night I was so sorry to bother people sleeping.
Anyways, I would come back with pleasure. Thanks Klaus!
