We stayed in a cottage in Wales, where the sofa and cushions were covered in dog hair, I vacuumed and washed the covers on arrival.
There was no television reception, and we had my mum with us who is an avid TV watcher, and lover of Soaps
The bathroom tiles were horrific, and smelt. Old dirty quarry tiles, that no amount of cleaning helped, and I used all the cleaners as we had small children, so had to cover the whole floor in towels.
Every town or large shop we went in I looked for a new toilet seat to fit, as the house one was old worn, wooden and nasty ( never found one )
.My emailed complaints were completely ignored, and never replied to by the company..
You are not being unreasonable.
We also stayed in a luxury log cabin in Scotland once, cheap dirty broken down hovel, next to the lake, attached to a caravan park, which had not been mentioned at all, with death trap old wooden cots for the children, a toilet with no lock, and no sign of any luxury anywhere.
It was absolute false advertising.
