We greatly enjoyed staying at Kateryna's apartment! The apartment was exactly as described, and Kateryna was an incredibly generous host. Kateryna had left us with a number of maps and information brochures, and offered us endless advice. She was very quick to respond to any questions or messages. The apartment itself was beautifully laid out and well located. The apartment is only two minutes from a Billa supermarket, and a short tram ride from the city centre. We stayed in January when it was snowing, and the apartment was always warm and inviting to come back to. We would highly recommend Kateryna's apartment to anyone looking for a clean, warm, central place to stay in Vienna!
