Along with nearby Malabar Hill, Cumbala Hill is home to the most number of billionaires in Mumbai as well hosts residences of prominent ministers. Billionaire Mukesh Ambani's $1.5 billion home Antilia is located here as well as numerous bungalows dating back to the British Raj.

It is also called Diplomat's Hill or Ambassador's Row by residents as many consulates and high commissions are located in the area.

There are two British-era milestones that were once used to guide horse carriages are present in the locality.
