We stayed a weekend in Munich at the end of March. The hotel is clean, the lobby area is big enough. The room did not have a basin which we would have appreciated a lot, but the bathroom itself was big and clean. The breakfast was DELICIOUS and had a large variety (a lot of healthy stuff which we prefer!). The staff was friendly.
The hotel gym was quite modest, I would say, for a hotel of 5 stars.
But the location is great, all the "best" boutiques in the same street, and everything just a few more steps (Höfbräuhaus, more boutiques and shops etc).
Munich is a nice city for a weekend stay - not too big, not too small, clean etc.
Nothing really to complain but compared to some other 5star-hotels we've been, this was a small disappointment though nothing special to complain about (except the gym).
