The pool was being cleaned an hour after we checked in, so we couldn't swim as by the time it was swimmable, it was too late in the evening for our young kids. The pool filter was broken so it was dirty when we swam in it. The waterfall feature wasn't working either.
The kitchen wasn't stocked with any basics, as we've always had in other holiday houses - salt and pepper, paper towel, cling wrap, etc.
The floors weren't thoroughly cleaned, so our feet got dirty walking in the house.
The shower in the main bathroom leaked from the wall so we couldn't use that shower. The basin in the main bedroom ensuite was clogged and drained slowly, so to wash our faces or clean teeth, we had to do so over the bath.
Overall it was a lovely house, but we expected higher attention to detail for the exorbitant amount we paid.
