Alexander's apartment has a nice layout and is conveniently located. Last floor vith lift, it is very luminous, clean and cosy. 15 minutes walk or 5 minutes bus (stop accross the street) from the opera and main city highlights. There is also a rooftop which is probably a great place to relax in summer. It was really a great experience and we felt immediately at home for these few days. Definitively a good place to recommend in Vienna.
