I stayed at Christine's place for about a week for a work trip at the UN, which is just a five minute walk away, and everything about the stay was perfect. Christine communicated all the information I needed quickly and her place was impeccably clean and welcoming. While I didn't get a lot of time to spend in the apartment, just about any waking moment I had I spent on the amazing terrace with a great view down the Danube, and the city center of Vienna. Christine's place will definitely be top of my list for any future visits I make to Vienna.
