Katharina's place is the cheapest that you could find in Vienna and the apartment is very charming, with beautiful plants and a wonderful balcony to chill in. All the basic amenities are covered, and the white tone of the apartment will suit you. The host and her roommate, (and all the neighbors) were extremely helpful and in times of a crisis, (we had locked ourselves out), everyone was extremely gracious in helping us. All in all, a wonderful experience.
