ernie,
Munich City is a nice hotel: friendly staff, the rooms are in good shape, and it has a good location. The only drawback is that there's no executive lounge.
I've stayed there twice since May. The first time I was upgraded to the business floor with a nice corner room. The second time was during Oktoberfest of this year so the hotel was sold out, hence no upgrade. Didn't matter because I had a suite booked anyway.
