You know real estate is hot when it only sits on the market for 24 hours. It also helps if the property has a glamorous history – and high-profile former residents.

That was the case for the first-floor apartment at 47 Grosvenor Square in London’s affluent Mayfair neighbourhood. The property, which was once used as a London home by the Onassis family, including Jackie Kennedy Onassis, hit the market with an asking price of nearly $US30 million. Within 24 hours, someone had scooped it up for $US22 million.

Wetherell, the real-estate agency behind the deal, kept the buyer’s identity anonymous but acknowledged the new owner is a Saudi billionaire. Peter Wetherell, founder and chairman of the agency, described the home in a press release as a “trophy property” – London properties that appeal to the global elite.

The apartment has yet to be restored since it was used by Onassis clan, and restoration could bump up its value even higher, to $US35 million. At 5,000 square feet, the home spans nearly the whole width and depth of the building, and it’s the only apartment in the building to have a 63-foot balcony overlooking Grosvenor Square.

Here’s a look inside.

The billionaire bought the home for his daughter, according to Wetherell, the real-estate agency behind the deal.

It’s the highest price paid for a single, unmodernized apartment in Mayfair this year. The last time a piece of Mayfair property listed above $US10 million sold in less than 24 hours was 10 years ago.

Over the years, aristocrats and politicians have flocked there. It was once home to Oscar Wilde and the US embassy. The building that housed the latter is now being transformed into a luxury hotel.

The residence used to be the London home of Artemis Onassis. It was used as a London pied-à-terre by members of the Onassis family, including Jackie Kennedy Onassis, in the 1960s and ’70s.

It’s the first time in over 28 years that the Onassis family’s Mayfair property hit the market and sold.

Before the Onassis family, it was first owned by Sir John Anderson, 1st Viscount Waverley, who was chairman of the Royal Opera House.

The building itself was erected in the late 1930s, designed in a palatial neo-Georgian style.

The residence has yet to be restored since its glamorous early days. A restoration could bring its value up to $US35 million, according to Wetherell.
