My family of 5 had a fantastic stay at Max and Raphael's beautiful and comfortable flat. They were wonderful with communications and very accommodating. We would definitely stay here again if we get the chance to come back to Vienna. Which I want to again one day.
The flat was close to a metro stop, surrounded by a plethora of restaurants, and a short walk to a nice little grocery store. It was also a short walk to Rathaus (city hall), Museum Quartiers and the Parlament Building to name a few. Oh we loved Vienna. You will too.
