Its sprawling mansions set in immaculate gardens are home to ageing magnates, foreign diplomats and members of the aristocracy.
So quite what the neighbours in this exclusive North London road will make of their latest resident is anybody’s guess.
Canadian pop star Justin Bieber is renting a 15-bedroom property there – for £108,333 a month, or almost £1.3million a year.
The 22-year-old singer plans to divide his time between his home in Los Angeles and the leafy London postcode over the coming months. It is thought he simply fell in love with the area.
Aree Rand, partner at leading estate Knight Frank, said: ‘This is one of the capital’s most luxurious homes and offers state-of-the-art facilities including an indoor and outdoor pool, a spa, tennis court, home cinema and wine cellar.
‘Roads such as this continue to hold massive appeal amongst the rich and the famous, and this is one of the few areas in London to offer larger properties with huge, secluded gardens.
‘The house also offers complete privacy, something essential for someone of Justin’s pop star standing.’
Bieber’s new home was built in 1910. By 2006 it was a rundown wreck which was bought for £5million by a property tycoon who spent millions renovating it.
