Spa Illuminata is like an oasis of calm in the heart of London's Mayfair. As a day-only spa, it is a beautiful venue to escape to on a visit to the capital, or during an extended lunch break.

Designed around the origins of the Roman and Greek spas, it exudes a timeless, classical elegance that makes you relax as soon as you step through the door. What looks like a small but elegant store from the outside, opens out into a huge cavern of relaxation. Ranked as the number one Day Spa in January's issue of Harper's Bazaar, it is not hard to see why.

A dedicated relaxation room and a choice of wet and dry steam rooms await visitors to help start easing the stresses before treatments begin.

The spa offers a wide variety of different treatments, with a particular focus on the wonderful Decélor products, which is unsurprising when you realise that it was started by the man responsible for bringing the leading French brand to us in the UK in the first place.

The facials offered by the spa are one of their staple treatments and are perfect for fitting into that lunchtime slot. Lasting about 75 minutes, they unusually begin with a short back massage to ensure you are fully relaxed before the deep cleansing begins.

But treatments are not all that the Spa offers. Aside from being able to hire the entire venue for the ultimate girls day out, Spa Illuminata also offers full make-overs, and with the John Frieda salon just over the road, will arrange for one of their top stylists to pop over and finish off your new look with new hair style.

And if you haven't got time for all of that, whenever you have a skin or bodycare treatment, the beauty therapists will take twenty minutes to reapply some light makeup so that you are ready to head straight back to the office as an added, complimentary treatment.

And if you don't fancy ruining those looks after all that hard work, the spa can also arrange a super-indulgent chauffeur service, picking you up from home or office and dropping you off wherever you need to go after.

Facial and bodycare treatments start at £85. Annual spa membership is also available offering a variety of discounts and free treatments each month. For further information visit www.spailluminata.com
