I had a wonderful time visiting Bonn, and the whole hotel experience was fully satisfactory. The reception staff were polite, knowledgable, and really helpful for tourists, offering local knowledge (and complimentary umbrellas when it rained). The room was excetionally clean, well equipped, warm, and comfortable. Housekeeping staff were polite, the entire building was clean and well maintained, I do not have any negative opinion of this hotel, and would use it again as my first choice if I ever return.
