Tanja's place is EXACTLY AS DESCRIBED. Super clean, super comfortable, and a very very reliable host with self-checkin and checkout. I highly recommend staying here if you want to live in the quieter parts of Vienna, in a super cozy flat.
Wifi was good! We were able to stream a Netflix movie, and watch Youtube with no problems. It might need to be set-up in the beginning, which takes only 2 minutes. Tanja sent us very clear instructions.
