we have had a holiday let, and at one time my parents acted as agents for a group of Brits with holiday lets overseas. The tenants were usually Brits, and it seems British owners know what British tenants want.
On the whole, we haven't done too badly, the odd sheet/towel/teaspoon which is usually by mistake. Most people are fine, but they do tend to do whatever they want, so we expect a fair amount of wear and tear.
But one house had a group of lawyers and their families come to stay.
About 3 families with 6-8 small children between them, including several in nappies. (big house)
The house was trashed. The cleaners had to call up for help (remember they get the time between 10 am and 3 pm to turn the house round).
The place was full of dirty nappies, just left anywhere, and not closed rolled up nappies either. Food smeared on everything - sofas, floors etc. Wet towels left festering in heaps, rubbish scattered everywhere and not bagged or put in bin and so on.
The cleaner commented - I think they have a nanny and cleaner at home, and didn't bring them on holiday with them....
