Owned by Sir George Meyrick, one of the richest men in Wales, the white-washed cottage has stunning views of the surrounding countryside including Snowdonia, Newborough Forest and Llanddwyn Island. It is hidden from view by a thicket and reached by a private road.
William and Kate will have very happy memories of the cottage now for rent
New tenants are being offered the same facilities used by William and Kate, which include a living room with an open fire and a dining room with French doors.
Until now it was not possible to report on the location of the house or even the layout because of security concerns.
Just last month the Duke spoke of how happy he and his wife had been there. The tranquil setting afforded them a retreat from the pressures of royal life.
The couple often walked on nearby beaches in matching wellies and Barbour jackets with their dog Lupo and enjoyed nights out in the local pub The White Eagle. Apparently William liked a pint of Bitter while the Duchess stuck to white white or mineral water.

Kate did the shopping at local supermarkets like any housewife and cooked her husband's favourite meal of roast chicken. With the arrival of Prince George she did have some extra help as the couple's housekeeper in London Antonella Fresolone is reported to have joined them. As did William's former nanny who came out of retirement to lend a hand with the little one.
Last week William, Kate, George and their dog Lupo moved back to the splendour of Kensington Palace, where their apartments in Princess Margaret's former home have been renovated at a cost of £1million.
His decision to leave the military after seven years was undoubtedly motivated in part by his desire to support Kate as much as possible in looking after their baby.
As well as focusing on fatherhood, the future King is looking forward to a new chapter involving more public service. Aides said he will take a year to decide which areas to focus on.

Promoting the conservation of endangered species is one of his main interests. William, who has often travelled to Africa to observe conservation projects at first hand, said George's arrival had spurred him on to act.
In a recent speech at the Tusk Conservation Awards, rewarding those who champion wildlife, he told guests their son has "a voice to match any lion's roar". He went on to say that as a new parent his thoughts had turned "to the world that dear George will inherit".
