Olga's place is amazing! it is very close to the city centre, and accessible everywhere you want to go, with a local Bahn station. It's also got a main HBF station - it's perfect. What makes this place 5/5 is Olga herself- a very friendly host who is super friendly and accommodating and responds to messages very promptly. I hope Olga's place will be available to rent often, it's a place I'll want to stay again when I come back to Vienna! Danke! From London :)
