My time in Katinkas apartment in Vienna during December 2015 was very pleasant and I thoroghly enjoyed my trip to this wonderful city.
The apartment was clean, very well equipped, is in an excellent location in a prestigouos area of Vienna and Katinka is a great host, who really cares about her guests feeling well.
I recommend Katinkas apartment for anybody visiting Vienna, either as single traveler or with a partner. Important for anyone renting a car, Katinkas apartment is in one of the few locations in Vienna which allows parking on the road without extra payments!
