So we just picked a hotel that was close to the center city so we could get around. We weren't expecting much but this hotel wasn't that bad.
The front desk was very friendly and the bell boy/man helped us with the underground parking.
We stayed in RM 237 on a Monday night and it was clean but simple. It could have been a lot worse for being a 3 star hotel. Price of 96 euro is a bit high, but I think you are paying for the location, it's not even a 5 min walk from the Hauptbahnhof.
Went to see the TollWood market and had fun there.
Breakfast was decent and now we are off to see some sights of Munich. The hotel is even letting us keep our car here until 1500, so that is cool.
Overall, if you need a place right near the Haupbahnhof, this is your place.More
