Returned recently from a 4* holiday rental- rates are almost £900 for the week- and the sheet on the master bed had a hole in it ( near the feet end) about the size of a 5p piece.
There was also a visible ( though small) old stain ( blood I think) under the sheet on the mattress cover.
I wouldn't use bedding like this at home for guests- even family coming to stay- so it is reasonable for me to now ping an email off and complain to the company? (They specialise in houses in one town only- all marketed as 'luxury' and have a portfolio of around 20 houses.)
