Andreas was a fantastic host. My family and I arrived in Vienna before he could get off work, but he instructed us to pick up keys to his flat from a friend of his who works just down the street...it was a cinch. His communication before and throughout our stay was superb. His flat was exactly as advertised and you can NOT beat the location...you can practically throw a stone and hit St. Stephen's Cathedral. If/when I find myself in the lovely city of Vienna again, I would not hesitate to stay at his place and recommend it to others without reservation.
