Munich is quite suitable for wheelchair users: most of the sidewalks are lowered to a height of 3 cm at street crossings.
However, there are some areas in the city center which are tricky because of cobblestone pavements or acclivties.

Click on the map - the red marked fields indicate the areas where acclivities and cobblestone pavements could get in your way.
Between the street "Rindermarkt" and the market "Viktualienmarkt" you can use the elevators in the shop "Kustermann" (Mon-Sat 9:30 a.m. - 10:00 p.m.) and in the "Hotel Louis".
