The Best Western Atrium is where the wife and I usually stay in Munich. Great breakfast, parking garage underneath the place, and a 5 min walk from the AltStadt. It's in a Turkish/ Arab area, so it's cheaper than the other Best Western, but all it really amounts to is that you have like 10 Doener shops to pick from on your way back from the bars! It's also only 2 blocks from the Oktoberfest grounds and 2 blocks from the main train station, for anyone who is interested. I think we payed 300 euro for one night during the Fest, but otherwise I think I remember under $100 a night.
