This property should be investigated. The first room had no barrier between the sheet and mattress. Mattress was filthy with various stains of various colors. I was told by housekeeping they are only required by law to put a fitted sheet on the mattress. The next room had a mattress pad that had not been laundered since there were stains of various colors on it. We immediately cancelled our reservation and went to a different hotel. Mattresses without barriers between the sheet and mattress is a health hazard.
