I would happily stay here again in the future: great location for exploring the city: right next to the metro and train stations, easy walk to the shopping street that leads to the central tourist area, and there's a late-night supermarket very nearby (for those not familiar with Vienna, it seems like all the shops close really abnormally early).
The high ceilings and comfortable furnishings add to the relaxed feeling of being at home, and the kitchen in well stocked with necessary items - cookware, cutlery, and cooking essentials like salt and olive oil - that make it a practical alternative to eating out.
