Do a search in this forum for hotel & munich and you should get some details. I was looking for similar information at the start of the year and got a good few responses. We stayed in a hotel called (I think) the Royal. I think I wrote it up in the original thread. There are a whole load of what look like reasonable small hotels around the main train station (hauptbahnhof). Certainly the one we stayed in was clean, popular, had a good breakfast, somewhat non-descript, fully functional.
