We spent 4 fabulous days in Andrea's apartment in September. It felt like a luxurious hotel suite with a fantastic power shower, plenty of storage space and a really comfortable bed. We made use of the washing machine (as by this time we had been travelling for over a week) and extensive use of his super fast wifi (faster than mine at home!). It's a mere 15 minute walk to Stephensplatz so the whole of district 1 is easily within walking distance. I would definitely stay here again if I return to Vienna.
