6 – Aman Spa at The Connaught, London, UK
This is the first spa of its kind to be built outside of an Aman resort. It has come to prove that even in a bustling city like London you’ll find an award-winning spa to enjoy.
Although small in comparison to other spas on this list with just five treatment rooms it can still offer its guests a lot. The therapists enjoy pairing techniques that are diverse with only organic ingredients.
