Many holiday homes in the Netherlands are not cleaned well, according to a study by consumers association Consumentenbond. Researchers regularly found e.coli, hair, fungus, insects, and stains on walls and mattresses while doing this study.
Consumentenbond had mystery guests visit 30 holiday parks across the Netherlands. These guests inspected the cleanliness of the rooms, also using a UV light to check for bodily fluids. Fourteen of the checked holiday parks' hygiene was not up to standard. Especially the walls in the kitchens and bathrooms showed problems.
