Very disappointing for a property advertised as 5-star My experience at Quellonhof Lasize fell well below what I would expect from a 5-star property. The issues were not immediately apparent, but while unpacking that evening, we found dead flies on the bed, bodily hair in the sink, and large cobwebs around the room and ceiling. These are basic cleanliness problems that should not be present in a room that has been properly cleaned and prepared for guests. I reported the issues to reception that night. We were offered cleaning at around 10:15 p.m., which was too late and inconvenient to be a reasonable solution after we had already settled into the room. When we raised the matter again at check-out, we were offered only a insulting 10% discount, which felt entirely inadequate given the seriousness of the hygiene concerns and the lack of a timely solution. For clarity, we were upgraded upon arrival; this was not offered as compensation or as a response to the cleanliness issues. We accepted the upgraded room, although we ultimately regretted it. Because it was located by the lake, there were noticeably more mayflies and mosquitoes. We understood that insects might be more common in that setting and therefore kept the doors and windows closed, but that does not explain dead insects, hair or extensive cobwebs being present in a room that should have been thoroughly inspected before arrival. Noise from neighbouring rooms was also extremely disruptive, making it difficult to relax or sleep and further highlighting the inadequate soundproofing. Overall, the property felt closer to a 3- or 4-star hotel than a 5-star property. I would expect significantly higher housekeeping standards, better soundproofing and a more appropriate response when serious cleanliness concerns are reported. Based on this experience, I would not stay at this brand of hotel chain again or recommend it to others.
