Side by side The Connaught vs Four Seasons Hotel London at Park Lane

The Connaught costs what every Mayfair five-star costs now, and what you get for it is the martini trolley, three genuinely excellent bars, Helene Darroze upstairs, and a staff that tends to know your name by the second day. That last part isn't a stray compliment. It shows up constantly, from the doorman keeping a family's taxi orders straight at breakfast to a bar manager remembered by name for small touches. The Connaught Bar alone is worth crossing London for, trolley-side vermouth selection and all, even if you never book a room.

The rooms are where the argument gets more complicated. Some guests land in a newly redone junior suite with a four-poster bed and love it; others get an entry-level room they call small, dark, or in need of a refresh, and the renovation has clearly been rolling through floors unevenly. The lobby's heavy floral scent splits people cleanly — some find it part of the charm, others found it genuinely bothersome enough to book elsewhere. And there's a real, if occasional, crack in the service reputation: a guest turned away for carrying a takeaway coffee, another laughed at over a phone charger, a bar door slammed shut eight minutes past a confirmed closing time. None of that is the norm, but it's not nothing either.

Book it for the bar and the restaurants first, the rooms second — ask what's been renovated before you commit to a category. If bar seating matters to you, know the Connaught doesn't have any at the counter itself; solo drinkers who want to perch tend to end up at Claridge's or the Rosewood instead. For everyone else, this is still the Mayfair address people return to year after year for the martini alone.

This is the hotel that put Four Seasons on the map outside North America, opened in 1970 as the Inn on the Park, and it still runs on the idea that comfort beats opulence. You're not paying for a jaw-dropping lobby. You're paying for a quiet street two minutes from Hyde Park, blackout curtains that actually work, and a staff that remembers your coffee order and your kid's name by the second morning. The location alone, tucked between Hyde Park and Green Park with Knightsbridge and Mayfair in walking distance, is hard to beat in this city.

The building itself splits opinion. Some love the residential warmth; others find the 1970s exterior flat and the renovated rooms oddly designed, with a doorless closet and a single light switch shared between the bathroom and the dressing area that means a 3am trip lights up the whole room. Breakfast is the other place it slips: the tasting menu at Pavyllon gets people genuinely excited, but the standard a la carte breakfast has produced repeated billing confusion, and one family's confirmed gluten-free order still arrived as regular bread, cold, on a birthday. Ask for a park-facing room; the rear rooms look onto a car park, not greenery.

Book it if you want London handled quietly and well: a hotel that solves jet lag and looks after kids without turning the stay into a production. Skip it if you're chasing the kind of history and drama you get at Claridge's or the Dorchester down the road, both of which trade some of this warmth for a grander sense of occasion. For a family wanting Hyde Park on foot and a bed that actually works after a long flight, this is still the one to book.
