Best for: Treatments with a view.
Hint: if your therapist asks how you’d like the curtains at the Four Seasons Hotel spa, the correct answer is ‘open’. As well as a posh Park Lane postcode, each treatment room offers floor-to-ceiling windows with killer views over Hyde Park. Of course, what’s inside counts too. Don a fluffy robe and squishy flip-flops, then pad toward the heat therapy rooms complete with sauna and pool. Its wide range of treatments includes massages, facials, wraps, scrubs and nail treatments, each using high-end products from brands like ESPA and The Organic Pharmacy. Afterwards, head to a dimly lit relaxation pod, where you can have a steaming cup of tea and some nibbles, while you stick on a pair of headphones and let the calming effects of your treatment really sink in.
