When in Munich, maybe for Octoberfest or more sophisticated pleasures like eating at the 3 star restaurant JAN, there is a choice of a few fine luxury brands - among them is Rocco Forte’s The Charles located by the old botanical garden not far from the main train station (and 5 min walking distance from said restaurant btw).
I stayed for one night to check it out and see if it is a good option in the Bavarian capital for my clients.
