I stayed in Katja's place for 12 days while working in Vienna. The apartment was spacious and modern with nice amenities (washing machine a plus). It was very close to the UBahn and supermarkets which made it easy to shop and cook for myself in the evening. Katja was great. Met me when I arrived, helped me when I accidentally touched the wrong button on the TV remote, and checked in with me to see how things were going. I highly recommend this apartment for others.
