Quick and as painless as can be. It's at the higher end of the price spectrum but you pay for what you get! Therapist didn't chat much so great if you just want to chill out, plus they play nice relaxing music.
The spa was clean and pristine, and it had a good calm ambience. Also a good value manicure in the Kensington area. However, the staff seemed overworked and the nail file used on me seemed suspiciously white,
