I stayed at Catherine's flat for a few nights together with my boyfriend and we felt very comfortable with her from the beginning. She has a very stylish apartment which is perfectly located for tourists, we almost reached anything by walk. She left us a selfmade vienna guide based on her favorite spots and also apart from that she helped us a lot to have a enjoyable time in vienna. I think it was the best choice we could have made and I would love to stay with her again anytime. We had a lot of nice conversations but she still left us enough privacy. So I would recommend her place in every way!
