We've stayed in three places in Munchen.
One was some budget place by the train station that isn't worth discussing.
Another was Hotel Torbraü Tal. We stayed there to start our RS tour so I didn't pick it and don't know the price. It was very fancy and right by the Isa Tor.
When I book for us on another stay, I chose Pension am Jakobsplatz. I would recommend it. Chris was super helpful. Breakfast was acceptable. The small room had a shared bathroom but an in-room shower. And, it was affordable and incredibly conveniently located. We rarely spend real time in our room so as long as the bed is comfortable and the room is functional (it was) then we liked the place. Oh! And he had a small honor fridge of beer. :)
