Great apartment - the space was perfect for our stay and has a classic Viennese apartment feel (massive rooms, super high ceilings, great hardwood floor). The kitchen was very well stocked with everything needed for a 1 week stay, there was lots of storage in the bedroom and the bed itself was very comfortable.
Christian and Jane were great hosts, very responsive and also very flexible on arrival/departure time.
Lastly, the apartment is conveniently located within 5 min walking distance of multiple tram and a subway lines - making it a breeze to get to Vienna's main attractions. Many cafes and restaurants around the apartment are also worth a visit, specifically Paco Restaurant, Cafe Weimar, the Statt-Beisl im WUK and Veganista III (ice cream).
