Guerlain Spa at Raffles London
- Where: 57 Whitehall, London SW1A 2BX
- What: A spa inside one of London’s most luxurious hotels
- Highlights: Treatments designed to soothe and relax
The Guerlain Spa at Raffles London may be a behemoth – 27,000sq ft across four floors – but it is serene, intimate and inviting, raising the bar for what it means to be a hotel spa.

Day guests, hotel guests, residents and members are welcome. The interiors, by Goddard Littlefair, are sleek, gentle and cocooning. Nine spacious treatment rooms are situated along the original Old War Office corridors, and therapists are trained across all treatment types, offering everything from facial sculpting and body scrubs to bespoke programmes.
In true Guerlain fashion, signature treatments are a tribute to the maison’s products; guests are invited to experience the benefits of the famous Eau de Cologne Impériale, which Spear’s was treated to during our most recent visit.

AIRE Ancient Baths
- Where: 2-3 Robert St, London WC2N 6BH
- What: Roman-style baths in the heart of London
- Highlights: The salted Flotarium complete with an exfoliation chamber
If you happen to be looking for an Andalusian-themed bathhouse on The Strand, turn in to Robert Street and head into the cavernous world of AIRE Ancient Baths.

The spa is housed in the former wine cellars of Peter Pan author JM Barrie – a celebrated previous resident of the 18th-century Neoclassical building. After a trip down the winding staircase, emerge in the sumptuous changing areas, where the sweet, heady scent of orange blossom – an AIRE signature – is wafting through the air.
Expect to be whisked away into the massage and treatment rooms upstairs; if you are lucky, your treatment will be conducted in Barrie’s former apartment. Experience anything from a green tea ritual to an earl grey soak or an argan oil massage, the latter of which Spear’s experienced on our most recent visit. If you like, you can even immerse yourself in a bath of Ribera del Duero red wine and enjoy the detoxifying benefits of the wine grape.
