I really liked staying at Kiki's flat. It was completely within walking distance to many of the main sights in vienna. It was clean and well cared for, with a nice view out the windows. It did get pretty hot up on the top floor, but the fan and open windows helped alot. There also is no elevator and it is quite a climb to the flat. Despite these small inconveniences, it was a wonderful place to stay while visiting vienna! I would definitely recommend Kiki.
