The apartment is super, excellently located just off Vienna's central ring, opposite a subway station, and over a cafe that does a great breakfast. The apartment was spacious and comfortable for our family of four, everything was clean and new, and the modular furniture very funky. Christoph and his family have done everything to make it as comfortable for a guest as possible. I was genuinely very impressed and would definitely stay again the next time I am in Vienna, and already have recommended it to friends.
