The Beaumont Hotel in Mayfair is the sort of place you might imagine Don Draper would spa – cool, retro and with interiors that leave nothing to chance. Replacing new-age music with soothing jazz, it’s not the girliest of places, but the treatments I experienced were excellent. I opted for the Total Relaxation Package (2 hours 45 minutes, £240), and they suggest you arrive early to make use of the sauna, steam room and cold pool – I did and it really helped get my body ready for my treatments. I then went through for my hammam treatment, which incorporated a cleanse and all-over exfoliation with savon noir, followed by a scrub, warm clay wrap and relaxing head massage. All rinsed and with baby-soft skin, I was moved into another room for a 60-minute full-body massage (to which I fell asleep). To finish, I received a Pai Pure Hydration Facial with cleansing, toning, mask, face massage and moisturiser.
