The room was great - clean with comfortable bed and bedding.  I found all the staff very friendly and helpful.
I enjoyed the breakfast.  Lots of choices, all fresh, including cereal, muesli, fresh fruit, selection of breads, eggs and bacon, cold cuts and cheeses. Also a nice selection of teas and coffee/espresso. There was nothing else that I would have wanted.  I saw that another guest complained that there were no eggs, but I never experienced that during my stay.  I found that the staff was on top of things, replenishing as needed and cleaning up after guests.
The only point that I wasn't thrilled with was the parking.  I was only able to park on the premises one night.  I had to find parking on the street otherwise, which was doable if you return to the hotel later in the evening.  It is a challenge during the day, so you may have to utilize paid parking, which is available.
Despite the parking, I would definitely stay at Lücke again and recommend without hesitation.
