The apartment was very nice, clean and confortable, we had a bit of trouble understanding the heating system, so the first night it was kinda cold in the bedroom, but later we figured it out.
Altough it's not far from the main atractions of Vienna it was still a considerable distance, and didn't have any type of market nearby, but we realized that was just how the city is laid out.
Romeo was really nice and helpful, giving us tips for our stay.
