The service was not pleasant. We came to Germany from Canada and stayed at several hotels prior to this one. This hotel was the only one to approach me during their continental breakfast to advise I wasn't meeting the "dress code". For breakfast.. with only 1 other couple in the room. The manager came down while I was mid meal and asked me to change into something more presentable and return to eat (she was presumably called by kitchen staff, who gawked at me as though they had never seen Victoria's secret silk pyjamas). I was terribly embarrassed. This hotel is no Fairmont and I was quite put together, with my hair and face put together. To interrupt me in the middle of my meal, tucked away in the very corner of the breakfast area and out of sight, was humiliating. They didn't charge me for breakfast, but the experience was belittling.There were also dust mites beside the night stand in the bedroom, but otherwise clean.
