I stayed for six weeks in total at Gerd's place on a short term work placement. In all that time I needed something that provided both functionality and value for money. The apartment delivered everything I could have asked for, with the added benefit of a great central location! It was excellent as a base from which to access the city. Gerd is a gracious host and I really appreciated the small details and efforts he made to make the stay more comfortable. I would recommend especially to singles or couples and I will definitely come back on my next trip to Vienna!
