I had 2 separate stays at this property last month. For my first stay I was in an older suite, and the minibar was full. I was told at check in it was all complimentary (I'm Diamond).
On my second stay, I had a newly renovated room. It was very nice. The minibar was empty, but I received the voucher for a couple of drinks at the bar downstairs. Had a decent red.
Great breakfast the next day too. All in all, this is a good option if you have a late flight in or early flight out and don't care about being in the city. And, of course, the train into Munich couldn't be easier.
