We spend three days in Vienna and had a great time while staying in this apartment. The location is superb and the apartment self was also perfect, everything we needed (towels, toilet paper, blocks for the dish washer) was there. It was very clean. Although we had an hour delay with our plane we were more than welcome. For the check-in in the evening they charged 5 euro, and because of the delay (we arrived at 01:00 in the night in stead of 23:30 we had tho pay 20 euro), but that was reasonable.
