Kiki's place was extremely easy to get to from the airport, and in a very very convenient location for seeing Vienna.
The apartment was clean and easy to be in, the kitchen was fully equipped and easy to use, the bathroom was big and beautiful, and we could even do our laundry!
From the street-side window we could see the city rhythm, and from the courtyard side some quiet and green.
One thing to note is that further down the block there are some red-light bordello type establishments, which is fine, but the johns walking around late at night were a bit unnerving to me.
