Roman was very kind to get in touch a week before our trip to arrange everything. The apartment is fine with everything you need in it and is located in the center of the city, close to the University campus. Josefstadt, where apartment is located, is probably the best district to stay in Vienna, as it is full of historic buildings, restaurants and cafes, and is close to Rathaus and the Ring. I would recommend Roman as a very good host and his apartment as very suitable for holidays in Vienna.
