The apartment was far above my expectations, even better than I have expected judging by the nice photos. I 've stayed there for 1,5 months being on a business trip and felt really like home! It is very conveniently located close to public transport (incl CAT to the airport and undeground) and only 10 minutes walk to the very heart of the city and within walking distance to all the major attractions. Spaceous, modern design, very clean, comfortable bed and linen, all the amenities and accessoires are there - actually one could hardly imagine anything better:) Cristoph is very hospitable and was very open and supportive with tips for best locations of food, etc. The place is highly recommended, I would definetely stay here when I come to Vienna next time.
