Yes a mistake was made in the cleaning department. I had watched television the night before and eaten some dried cereal on the sofa. Some of the crumbs spilled out onto the floor and and the bowl was left in the sink. My bad! It was dark and I didn't catch it and the next day Lisa and her family arrived. The cottage had been completely cleaned before her arrival as is always the case and of course the sheets were washed..I would never ever consider making a bed with dirty sheets. It was an honest mistake and since there was not a lot of communication about it between I and my guest there was no opportunity to explain it or rectify it in some manner. I do encourage quick communication if there is a problem.
