The Duke and Duchess of Cambridge moved into Nottingham Cottage last week, a small residence in the grounds of Kensington Palace.
The cottage, known as Nott Cott, is a cosy two-bed that was previously occupied by Princess Diana's sister Lady Jane Fellowes and her husband Sir Robert Fellowes, the Queen's former secretary.
William and Kate rent a farmhouse near the Prince's search-and-rescue base in Anglesey, and until recently shared living quarters with Prince Harry at Clarence House. The couple will now live in the cottage at weekends when they are in London until they decide on a more permanent base.
The Daily Mail reports that they are tipped to take Apartment 1a in Kensington Palace, a lavish 19-room suite that was once the home of the late Princess Margaret.
The couple reportedly also considered Apartments 8 and 9, the former marital home of Charles and Diana where William grew up, but Kate is said to have been uncomfortable with the idea.
Apartment 1a, which is packed with priceless antiques, currently belongs to the Historic Royal Palaces which uses the space for exhibitions and offices. It has been open to the public since 2004.
A source has said that Nottingham Cottage is "very sweet" and told the Daily Mail that Kate has been overseeing the redecoration. "Although it's not huge it's their own space and they are delighted with it," the source told the newspaper.
