I am in Vienna as exchange student and stayed at Ruth's room three first weeks of my exchange. Ruth was amazing host: when I got to the apartment, she had left me a pair full of useful tips and things to do in Vienna. Also her flatmates were friendly and eager to help in any situation, which made me feel comfortable during my first days in an new city.
The apartment and room are certainly very comfy and the room has also lots of space! The apartment is located near to U Bahn and it is also easy to walk to places. Still it was located in a peaceful area so there wasn't too much noise to disturb.
I totally recommend this room and want to thank Ruth yet one more time!
