Royal fans around the world were shocked after it was revealed on Thursday that King Charles had to go to hospital for a “short period of observation” after experiencing side effects from his cancer treatment. Although the monarch, 76, is now back home, it is believed he was at The London Clinic, a hospital which treated Charles and Princess Kate last year when they both required surgical procedures.

While the idea of a hospital may generate negative thoughts of busy corridors and long waiting times in the minds of some, this is not the case when it comes to The London Clinic. Since being founded in 1932, the hospital has gained a worldwide reputation for the exceptional care it offers patients. As well as treating King Charles and Princess Kate, the list of famous faces it has treated before is also impressive and includes former Prime Minister Clement Attlee, US President John F. Kennedy and Hollywood legend Elizabeth Taylor.

As reported by The Mirror, the King and Princess Kate also aren’t the only royals to have been treated at the hospital before.

Prince Phillip and Princess Margaret are also believed to have been patients.

The service there includes patients' own concierge service and rooms that have a number of impressive features such as an electronic patient-controlled bed, en-suite bathroom, a safety deposit box and a TV.

The hospital, which can be found on Devonshire Place in London, also offers an impressive food menu which includes fish from Cornish boats and meat from historic Smithfield Market.

As well as ensuring patients receive top care, the hospital has continued working on the treatments they offer, which use cutting-edge technology.

To access care at the hospital, patients have multiple payment options for the fees, including the ability to pay upfront, through finance options, or with private health insurance.

The hospital also offers all-inclusive packages for some treatments which means patients will only ever pay one price that won’t change.
