Walter's place is excellent in all respects. It is very conveniently located across the Danube from St Stephan's square, within minutes from all the attractions of the city center, and also from loads of restaurants and shops. It is also close to public transportation, with the underground a couple of minutes away, and a great departure point to all the other attractions in Vienna (e.g. Museum Quartier or Prater). The apartment is very spacious, clean, highly comfortable, with all it is needed in terms of amenities and essentials. The neighbourhood is quiet, a great residential area. There is a grocery store just across the street from the apartment, as well as a bakery at the juncture with Danube's canal.
A special remark about Thomas, who manages Walter's place. He's not only been attentive, helpful and easy to communicate with all throughout the process, but also extremely kind and friendly. He took the time to give us an overview of Vienna, recommend places to go, help us with the orientation on the map. He also helped us with an early check in. He is a real asset to the propriety and we owe him a big thanks!
