Our room had a broken bathroom heater (the only thing combating mold and dampness) and a broken TV. When we asked for help through the recommended chat, we literally received a "yes?" as acknowledgement and a "no." as an answer. Further questions were simply ignored for a while and then we received (literally), "hello, I wouldn't know. It usually works." When we asked in person, we got interrupted for speaking fluent German, a dismissive "not-my-problem" attitude, and we were told on multiple occasions that a technician would come "the next day." They were never able to give us a timeframe and nobody ever came. Otherwise, the stay was great. Living space and amenities were great, complete with a yoga hall, gym, dining area and plenty of lounge space. The hotel is conveniently near the train station, although the surrounding area is all construction or industrial parks right up to your window.
