This was a really lovely little studio flat, wonderfully designed and full of touches that make it a really pleasure to stay in. The compact space feels larger than it is, and genuinely fun, cosy and atmospheric. The neighbourhood is also pleasant with three classic Vienna cafes not far off (Jelinek, Rudigerhof and Sperl), plenty of shops should you need them, and a underground line direct into the city just a block or so away. Andrei's father, who introduced me to the flat, was also lovely and helpful. As with all of the 'high-bed style' studio flats, you have to feel comfortable with the higher level, but for many this is a 'fun feature'.
All in all, this was the space that I enjoyed most in all of Vienna - I recommend it highly!
