Katharina's apartment is exactly like the photos shown.
Katharina and Peter very kindly accommodated our early check-in.
On the days we were in Vienna, it was rainy and then snowing, and our clothes got wet and dirty. When I let them know we would like laundry detergent, they replied quickly and laundry detergent was immediately outside the door along with a drying rack! They were also helpful with emailing us taxi options to the airport.
One personal story I would like to share is that -- when I was choosing which apartment to rent, I was considering ones with and without elevators, and since I thought we are young, I didn't' think it's an important factor. Thank God I chose Katharina's apartment in the end because I injured my leg during the trip and Katharina's apartment has an elevator!!! If I were to choose the other one without, then I would have been in deep trouble!
