Mouldy mattresses, stained duvets and dirty toilets have been found at budget hotels by a consumer rights magazine. Which? Holiday magazine said it found poor cleaning standards at some London and Manchester hotels run by budget chains Ibis and Travelodge. The dirtiest toilet was at Ibis Euston in central London, it said. Spokesmen for Ibis and Travelodge said the levels of uncleanness found did not present a health risk to customers, but they would act on the investigation.
