We really enjoyed staying at Emil's place. The location is excellent - very central and you can walk easily to many places of interest, but quiet because the building is set off the street. The apartment is light and spacious (a good size for a couple) and very clean, on the 8th floor (with a lift). It has two balconies facing different directions, so you get lots of good light. There is plenty of wardrobe space to put your things, and good wireless internet. Emil was very friendly, flexible and helpful with recommendations for restaurants, cafes and bars around Vienna. We would return!
