When asked how you’d like the curtains at the Four Seasons Hotel spa, definitely, definitely say ‘open’. Each room here offers killer views out over Hyde Park to accompany its spa treatments. Therapy rooms come complete with sauna and pool, while the the wide range of treatments includes massages, facials, wraps, scrubs and nail treatments. 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.
