I had a limited time to spend in Vienna and the historic centre with KHM was second on my list after the zoo.
It is a magnificent place, very beautiful, and very visitor friendly.
I spent half a day just looking at the buldings from the outside and strolling alng the streets and squares of the "BURG" and "Neuburg". This city within a city is perhaps the most beatiful complex I have ever seen. It is extremely well maintained and visitor friendly.
Few busses go through the Burg-Neuburg, so one can both walk, or ride a bus, or ride a horse cart. Plentiful possibilities to sit and admire the historic centre, because it is not enough just to walk by. Watching the enormous buldings, one discovers multiple statues, with tiny details, with gardens surrounding them, fontains amids trees and green grass, and then back to the impression of the whole, back to ancient history and myths as seen by emperors and artists. A lot for present day tourists to enjoy.
Tips: sensible shoes, and some reading in advance
