A guest and his two co-workers just stayed at my place. This evening, he sent me a message that while he loved the location of the place, the bed had a bad smell that prevented him from sleeping well. After investigation, he said one of the pillows and one of the blankets had an odor though the sheets were clean. He also said that a hotel would have refunded his money.
Certainly I want him to be happy and am not happy that his sleep was poor, but I'm not sure what to do.
I wish he had said something during his five nights at my place. I did check in with him during his stay but didn't receive a response (we had communicated through Airbnb messenger a number of times, so I know he received my messages).
Today, I did wash the blanket he mentioned but didn't notice any particular smell when I was putting it in the washing machine. (I also didn't search for the smell as I didn't receive his message until after the fact.)
Does Airbnb have a police around this? Any suggestions about what I should do?
