I stayed 4 weeks in Judith's apartment in July 2016 as a solo traveler.
Judith is well organized and available. She provided me with useful touristic advices and left leaflets that helped me organize my stay too.
The apartment matches the description and the pictures. It has a nice view on the roofs of Vienna: a lot of light, sun in the afternoon, and sunset colors. I cooked every day without problem and could watch the football matches of Euro on TV. Wifi is good too.
The location is good: less than 20 minute walk to Stephansdom, metro-tram-bus-city bikes-supermarkets around the corner. And the district itself is a nice place: I suggest you take a walk to the nearby Augarten (5 minute walk) and its gardens-cafés-restaurants-museum-summer cinema and so on... The Prater is only 10 minute walk away, and includes not only the world famous Giant Ferris Wheel (Riesenrad) but a whole amusement park and a huge park with many leisure activities - even a 13 kilometer hike (called Stadtwanderweg 9). Donaukanal (10 minute walk) is worth visiting too.
I enjoyed my stay in Judith's apartment and I warmly recommend it.
