We're looking at carpets for a flat we will be renting out. We've had quotes from a local carpet supplier, CarpetRight and Tapi. We were most impressed by Tapi and they agreed to match the price of the local supplier. The local shop were selling carpets which were advertised as guaranteed stain proof. The Tapi ones don't say that but the woman in Tapi said they're all made of polypropylene so will they are all stain proof. Does anyone know if this is the case? Many thanks.
