We noticed it was a funny murky colour but we got in.
Why would you do this?? Surely in just about every advert for villas or hotels, they show wonderful clear pools, so why would you or any of your family voluntarily enter a pool which was, as you described, -"murky"!, or even slightly so??
Not only that but, as you said, you all went in again, more than once!!
Now you come to this forum complaining when you should have used your common sense when looking at the state of the pool. Perhaps you and your husband and family should have thought about what the implications of swimming in dirty water would be . Seemingly not.
I am not as trusting as most ,so I may be a bit cautions here but, it looks to me like this could be a "Compo" claim on its way to a villa owner!!!
