I stayed here with two friends and we loved the place! Only disadvantage of the place was that the apartment is almost in street level and the living room window which looks at a main street can make you lose privacy when open. Check-in went fine, despite a slight delay, and we got to talk a little with grace who was very nice and helpful. She also sent me a list of tips and recommended activities in vienna. The place was clean, not too big but it was perfect for the three of us. The beds were good size and comfortable. The kitchen was clean and well equiped, only missing a frying pan.
