I have been here in March 2015 for a one night stay. It has long been since I stayed there before (I prefer Hilton Munich City for the location and being a returning guest there). I think Hilton Munich Park improved with a renovation accomplished. This time I was Diamond and I enjoyed the executive lounge a lot. They accommodated my preferences in my profile. Pre-arrival upgrade has been from a basic room (booked) to an executive floor room facing the park (Englischer Garten). Staff were pleasant.
