World-class teaching in a world-class environment, that’s pretty much it. In my opinion, here the rankings do reflect reality well. Lots of subjects you can choose from, great facilities, and the quality of teaching is also generally quite good.
In terms of the city itself, Munich is just great in all seasons, in the very centre of Europe and full of things to do and see, festivals and culture. The university though, is located outside of town (25 mins away from the centre), which should be considered.
