Aman Spa

While located beneath the Connaught Hotel in less-than-relaxing Mayfair, once you’re being massaged in oils from the continent of your choice in the heavenly Aman Spa, ensconced in hot towels on a heated bed, and being murmured to in hushed tones by your barefoot therapist, you won’t believe you’re not in a Malaysian beach spa. The spa also features what must be London’s nicest swimming pool, black tiled and complete with waterfall. A half-hour treatment costs around £70.
