An unusual, pleasant experience. Very peaceful surroundings. The atmosphere captures the monastic peace and bliss of idealized monastic life. The rooms are not just clean -- they are relaxing and smell fresh, aromatherapeutic! Beautiful residential neighborhood, oldest burg of Dusseldorf. Surface metro train nearby, nice neighborhood restaurants. PROBLEM: German cyclist are famous for their attitude of entitlement, which reaches the point of not slowing down for pedestrians. Hundreds of tourist are hit each year by cyclists who would rather collide with a human body than forgive its invasion of the bike lanes that border sidewalks. As I walked back to the hotel after dinner, in the rain on the desert boulevard, I was rudely shouted at by a passing cyclist, who intentionally rode fast by me to teach me a lesson for walking in the middle of the drive leading to the hotel. Astonishingly, he was the night porter of the Hotel MutterHaus riding to his 10 PM shift. He must have known I was almost certainly a guest at his hotel, but it was more important to signal his disapproval of my walking style. Upon departing next morning, I wrote a stinging description in my guest comments (which included compliments for all other aspects of my stay), and the hotel manager wrote me an email to apologize while I was still in my taxi to the airport. Overall an excellent hotel, but the psycho biking porter needs reeducation and treatment before he is allowed in public again.
