According to “The Adventure of the Illustrious Client”, Holmes and Watson ‘had a weakness for the Turkish bath’, which means they liked the bath very much. It says the Turkish bath is located on the Northumberland Avenue in London.
When I looked at Google Map, I found a spa called ‘Thai Square Spa’ next to ‘Sherlock Holmes Pub’. I think this is the place for Holmes and Watson’s favourite.
The pictures on the official websites are gorgeous, and I hope I can go there someday!
