London has too many good hotels, which is the actual problem
London doesn't have a shortage of great five-stars — it has a surplus, which is its own kind of trap. Ask five well-travelled people where to stay and you'll get five confident, contradictory answers, because the top tier here isn't separated by quality so much as by kind. Claridge's, The Lanesborough, The Berkeley and the rest are all genuinely excellent and genuinely different animals. The question was never "which is best" — it's which kind of good you're buying, and what you're trading away to get it.
Where people actually stay
The Lanesborough is the one people invoke when they want to talk about service as a discipline rather than a nicety — butlers who remember a thermostat setting from a stay two years ago, doormen who use your name before you have given it. It's also the one with no pool and, in places, single-sink bathrooms in rooms you'd expect better from, so the trade is real: you're paying for staff, not square footage.
Claridge's is the grande dame that still delivers on the myth more often than not — Art Deco arrival sequence, Foyer tea, long-tenured staff who convert first-timers into repeat guests. The caveats are structural: it's a big machine, so consistency dips at scale, and there's construction outside the entrance right now that guests inside say doesn't touch the actual stay.
The Berkeley is the pick if you want a rooftop pool and the Surrenne spa in the mix — genuinely one of the better wellness offerings among this group — plus Cedric Grolet's patisserie. The catch, repeated often enough to matter: that pool is frequently unusable for families due to crowding or age rules, which undercuts the exact thing being sold.
The Peninsula London is the newest and the most engineered — walk-in wardrobes, twin-sink marble bathrooms, a cigar lounge people rank among the best in Europe, a house fleet of Rolls-Royces. It's also the one where the room product can feel like it could be anywhere, and where operational edges — a slow breakfast, an ugly incident over bicycle access in the courtyard — haven't been fully sanded down yet.
Belmond The Cadogan and COMO The Halkin are the small, townhouse answer to all of the above — 67 and 41 rooms respectively, no meaningful spa at either, standard rooms that run small. What you get instead is a general manager and staff at The Cadogan who get credited by name for setting the tone, and at The Halkin, the same handful of staff names — Pammy, Debra, Morris — recurring across years of separate accounts.
Who each is for
If service-as-theater is what you're after, The Lanesborough or Claridge's. If you want a pool and spa alongside the heritage, The Berkeley, accepting the family-hours caveat. If the room itself needs to do the work — engineering, tech, a cigar lounge — The Peninsula. And if you want London to feel like a residence rather than a hotel, and you're willing to skip the spa entirely, The Cadogan or The Halkin.
There's no single best hotel in London — there's a best hotel for what you're willing to give up, and every one of these makes you give something up.
We haven't stayed at any of these ourselves — this is what two years of dated guest reports keep saying, not a first-hand ranking. The full guide, with room categories and rates, is at London hotels.
