Christoph and Vedi's apartment is mod, airy, spacious, clean, well-appointed with comfortable furniture and comfortable beds, and perfectly located for visiting Vienna's phenomenal museums, lovely gardens, and old districts. There is a great little cafe conveniently located on the first floor and public transportation right outside the door. It was perfect! We visited during an extended extreme heat wave and the apartment is not air conditioned, but Christoph and Vedi were incredibly amenable and supplied us with fans immediately upon request. We highly recommend this contemporary and comfortable apartment.
