Kiki's apartment is conveniently located, only about a 10 minute walk from the TU Wien building where I was attending a conference. This is also very close to the historic center of the city. The apartment is clean, nice-looking, and has all the facilities one might want, including shower, bathtub, kitchen, and washing machine. It was quiet and very nice.

I didn't actually have the chance to meet Kiki face to face, but she was very good with electronic communication prior to my arrival.

I would definitely recommend staying here to anyone!
