Arrived for a 5 night stay and left after 1! Found the house to be dirty and horrified to find clear evidence of mice!
The unhygienic conditions, with clear health and safety implications included: mouse faeces (in my dog bowl 40 minutes after arrival - leading us to store all food in our car overnight), dirty kitchen cupboards/equipment (more droppings) and grubby household items, live ants and flies throughout the property. There were multiple plugged in vermin repellant devices, situated in the kitchen and upstairs.
The owner said they would send someone to sort the problem, I was asked if it was OK to put poison down, absolutely not. While my dog may not find a baited trap it was quite possible he would find a dead or dying poisoned mouse!
After a two day debate with the agent and owner, we were eventually moved to alternative accommodation (not before I had to pay for an overnight stay elsewhere). I could write more about this discussion and events but I have chosen not too.
Could be a lovely coach house but sadly it has been severely neglected and requires a thorough deep clean and visit from pest control.
