Everything about this place is top notch: location, lay out, space, beautiful interior design, original oak floor, cleanness, well-matched utensils, full availability of home appliance, high quality bedding. The building is located in a very classic and central neighborhood. As a matter of fact, the upstairs neighbor is a duchess and an old aristocratic family is living in the building right across street. My wife and I didn't get to meet Oscar, but his elegant mother spend one hour explaining to us everything about the apartment as well as giving recommendations for the best restaurants / museums in Vienna. Our Vienna stay couldn't have been better!!
