The house was nice, but not clean. I had to look under the couch to retrieve a toy and it was totally filthy. This was visible when coming up from the downstairs area too. By itself, this would not have been an issue, however it got us looking at other areas and just noticing more and more. Every surface was either covered in dust or had been wiped with a dirty cloth. There were old food scraps and dirt and dust in the kitchen utensil drawers, and the canopy filters were dripping old oil into the food cooking on the cooktop. Also there weren't many kitchen utensils to use, and what there was was most broken. To the extent that the tongs had to be used like chopsticks!
My partner found an old sewing needle in the carpet as it stuck into her foot.
Next, there was no gas for the BBQ, and when the refill was delivered, it was dropped over the fence, and left for us to take upstairs and fit to the BBQ. Finally when we managed to have a BBQ, we noticed the hornets that had burrowed into the outdoor table and started to swarm when we sat down to eat.
Lastly, the lawns weren't mowed when we arrived, and were done a day before we left, leaving the kids no outdoor area to play in until the last day.
While none of these issues are significant in isolation, the culmination of all of them resulted in a very disappointing stay given it was one of the most expensive options available.
