Want new, design-driven wellness? Look at Claridge’s Guerlain spa or the Bulgari subterranean aesthetics.
Practical booking tips (so you don’t waste time)
Book spa treatments in advance (especially weekends). Many hotel spas limit external bookings on busy dates.
Ask about access — some spas reserve pool access to in-house guests during peak times; pre-book a “spa day” package to guarantee pool time.
Remember transport — most top hotels are within a short walk of Piccadilly, Knightsbridge, Green Park, Hyde Park Corner, Bond Street or Charing Cross stations. If you want door-to-door convenience after a long flight, include a TRANSFER SERVICE inside your travel plan.
Check age rules — some hotel spas restrict pool or thermal suite access to adults during certain hours.
