Well, I only visited once, but maybe can shed some light:

The public transport is as good as any European town, with bus and regional trains that will take you almost anywhere. There is a somewhat small (by European standards) airport.

It is about 1 1/2 hours from Munich, DE by train.

This is Mozart's hometown, and it is in close proximity to mountains, skiing, mountain biking if you are into that sort of thing.
