KKenneth Camillerilocation is A+. 2 minuite walk to the Heinrich underground station which takes you straight to the Messe. Hotel is nice. strange layout but its a medieval building so its part of the charm. Front desk leaves much to desire for a 5 star hotel. the room is ok. was given room 131. mattress was collapsed and definitely not commercial 5 star hotel standard.felt more of a foam cushion than a mattress with just 10 cm height of cushioning. i am 1.87 mtrs height and 110kgs. the mattress went concave when i lied down and my upper back muscles namely rhomboids and lats felt it badly in the morning. Advised the front desk who replied nothing can be done because all mattresses are like that. i don't insist or complain further if i am refused or rejected the first time i ask. on my checkout i advised front desk whose manager was present and i advised i was very happy with location but not with bed. i had no reply from her and she moved away stating in awe that no one had such an issue. on a positive note the breakfast operators who were very attentive and courteous at all times. for 950 euros for 3 nights i think they are very lacking in not being able to provide the basic hotel service of a good nights rest.
