Diana, Princess of Wales's mother bought her a flat on her 18th birthday in which part of London?

Diana, Princess of Wales (born Diana Frances Spencer; 1 July 1961 – 31 August 1997) was a member of the British royal family. She was the first wife of Charles, Prince of Wales, and the mother of Prince William and Prince Harry. Diana's activism and glamour made her an international icon and earned her an enduring popularity as well as an unprecedented public scrutiny, exacerbated by her tumultuous private life.

In July 1979, her mother bought her a flat at Coleherne Court in Earl's Court as an 18th birthday present. She lived there with three flatmates until 25 February 1981.

Earl's Court is a district in the Royal Borough of Kensington and Chelsea in West London, bordering the rail tracks of the West London line and District line that separate it from the ancient borough of Fulham to the west, the sub-districts of South Kensington to the east, Chelsea to the south and Kensington to the north. It lent its name to the now defunct eponymous pleasure grounds opened in 1887 followed by the pre-World War II Earls Court Exhibition Centre, as one of the country's largest indoor arenas and a popular concert venue, until its controversial closure in 2014. The area has long been known as "Bedsitter Land" with many of its stuccoed terraces converted into hotels and hostels.
