No wonder, then, that William, Kate, and the Middleton clan enjoyed a stay at the eight-acre luxury property back in 2006, with Gary kindly lending the house out.
The businessman revealed: "Carole asked if the family and Prince William could use it. We organized a whole itinerary for them, including going over to a neighbouring island on a boat… they all had the Ibiza experience from mud baths, to (nightclub) Pacha, to learning how to mix music."
Gary Goldsmith's arrest
The 56-year-old was arrested in 2017 following an argument with his wife, Julie-Ann, which took place in the street in the early hours of the morning.

Gary and Tallulah were guests at Pippa Middleton's wedding to James Matthews at St Mark's Church in Englefield, Berkshire on 20 May 2017, with the bride's uncle sharing a photo of the pair in their finery to Twitter on the big day.
Talking about the difference between his two nieces, Gary commented: "They are different. Kate works really hard at everything. She is brilliant at whatever she turns her hand to, but works at it, throwing herself into everything. Whereas Pip, everything seems to come very easily."
What else has Gary Goldsmith said about Kate and the royal family?
Speaking about Kate's marriage into The Firm, the businessman told ITV: "It’s a fairy tale beyond fairy tales."
He went on: "We come from really humble stock. My father was a painter and decorator, mum was an accounts clerk and their eldest granddaughter was at Westminster Abbey about to marry the future king of this country."
The Day Will and Kate Got Married is on Wednesday night at 9pm on ITV.
