Excellent apartment just steps away from the attractions of central Vienna. It is easy to reach with excellent public transport links, as well as amenities including several supermarkets, corner shops, restaurants and car parks, and there is also easy parking on the street (purchase tickets at the corner shops).
The apartment itself is spotlessly clean and quiet and of a decent size. The kitchen has a dishwasher and a bean-to-cup coffee machine and a microwave, and for those staying longer there is a washing machine. The bathroom has a shower that provides decent hot water at constant temperature. The apartment was the perfect temperature while we were there (winter), and while I didn't see any air-conditioning, the massively thick walls and high ceilings should ensure summer is comfortable.
Denise is a fantastic host who responds very quickly to messages and is very helpful: she made the entire process of checking in and checking out utterly effortless and fast.
