You’ve probably walked past it a dozen times if you’ve ever wandered down Piccadilly. It’s that building with the massive living wall—literally a vertical forest crawling up the side of a posh London corner—right across from Green Park. Most people just take a photo of the greenery and keep walking toward the Ritz or the massive storefronts of Fortnum & Mason. They’re missing out. The Athenaeum Hotel Mayfair is, honestly, one of the weirdest and most wonderful hospitality icons in the city. It doesn't feel like a corporate chain. It feels like someone’s incredibly wealthy, slightly eccentric uncle decided to open a guest house and filled it with velvet, whiskey, and a weirdly specific amount of Hollywood history.
It’s independent. That matters in a city where every big name is being swallowed by global conglomerates.
The Spielberg Connection and Other Mayfair Myths
Let’s get the "celebrity" thing out of the way because it’s actually a huge part of why the place feels the way it does. Back in the day, this was the unofficial headquarters for the Hollywood elite in London. We aren't just talking about a random stay by a reality star. Steven Spielberg famously edited E.T. in one of the residences here. He even installed a cinema grade editing suite in the room. Imagine being the housekeeper knocking on the door to change the towels and seeing a young Spielberg cutting together the most famous alien movie in history.
Harrison Ford, Elizabeth Taylor, Marlon Brando—they all lived here for stretches. Not just stayed. Lived. This history informs the service. It’s why the hotel feels more private than its neighbors. The staff at The Athenaeum Hotel Mayfair have this "seen it all" vibe that is deeply comforting. They aren’t going to fawn over you in a way that feels fake, but they’ll remember if you prefer a specific type of gin or if you need a quiet corner to take a Zoom call.
That Vertical Garden is More Than a Gimmick
Patrick Blanc is the guy behind the wall. He’s a French botanist who basically pioneered the concept of the "Mur Végétal." When it was installed, it was a massive risk. In London’s climate, keeping that many plants alive on a vertical surface is a nightmare of engineering and irrigation. But it works. It acts as a natural insulator, and honestly, standing under it makes the air feel about five degrees cooler and noticeably cleaner, which is a miracle considering the buses chugging down Piccadilly ten feet away.
The rooms inside mirror this. They went through a massive renovation a few years back, steered by the design team at Kinnersley Kent Design. They ditched the old-school "grandma’s parlor" look for something much sleeker. You get floor-to-ceiling windows. If you’re lucky enough to snag a Park View room, you’re looking directly into the canopy of Green Park. It’s like living in a luxury treehouse.

What People Get Wrong About Mayfair Hotels
Most people think Mayfair is stuffy. They think they need to wear a tie to get a glass of water.
The Athenaeum sort of breaks that rule. Yeah, it’s expensive. Yeah, it’s high-end. But it’s surprisingly kid-friendly. They have a dedicated "Children’s Concierge." Most five-star hotels treat kids like a liability that might smudge the marble. Here, they have kites for the park, milk and cookies at turndown, and actual activities. It’s a weird juxtaposition—the place where Brando got drunk and Spielberg edited masterpieces is also arguably the best place in W1 to bring a toddler.
Then there are the residences. These are separate Victorian townhouses located right behind the main hotel on Brick Street. If you want to feel like a local—a very, very rich local—this is where you stay. You get your own front door. You get a kitchen. But you can still call down for a club sandwich at 3:00 AM.
The Whiskey Problem (Or Solution)
If you like bourbon or Scotch, the bar here is a bit of a pilgrimage site. They don’t just have a "selection." They have a library.
- The Whiskey Bar features over 100 different labels.
- The staff actually knows what they’re talking about; they won’t just point to the most expensive bottle.
- It’s dark, moody, and tucked away. It’s the kind of place where you could negotiate a business deal or hide from a panoramic London rainstorm for three hours.
I’ve spent time in a lot of Mayfair bars. Most of them are "see and be seen" spots where people spend more time looking at their phones than their drinks. The Athenaeum’s bar is the opposite. It’s a hideout.

The Food Situation: 116 at The Athenaeum
The main restaurant, 116 at The Athenaeum, focuses on British ingredients without being "twee" about it. It’s not trying to reinvent the wheel with molecular gastronomy or foam made out of pine needles. It’s just good.
- The Afternoon Tea: It’s a London staple. They offer a classic version, but also savory options for people who don't want a sugar crash by 4:00 PM.
- The Breakfast: Get the full English. Don't overthink it. The quality of the bacon alone justifies the price.
- The Vibe: It’s bright. Lots of natural light compared to the moody whiskey bar downstairs.
A Note on the Spa
It’s small. Let’s be real. If you’re looking for a sprawling Olympic-sized pool and ten different saunas, go to the Bulgari or the Corinthia. The spa at The Athenaeum Hotel Mayfair is intimate. It’s in the basement, and it feels like a secret bunker. They use Temple Spa products. It’s perfect for a post-flight massage to get the kinks out of your neck, but it’s not a "spa destination" in its own right. It’s an amenity, and a good one, but know what you’re getting.
Is it Worth the Price Tag?
London hotel prices have gone absolutely insane lately. You can easily spend £800 a night for a room the size of a shoebox in a "trendy" part of town.
The Athenaeum isn't cheap, but you’re paying for the location and the space. You are thirty seconds from the Tube. You’re a five-minute walk from Buckingham Palace. You’re right in the heart of the gallery district.
More importantly, you're paying for the lack of pretension. There’s a specific type of traveler who hates the gold-leaf-everything vibe of the traditional Mayfair hotels. If you want luxury but you also want to wear sneakers and not feel like the doorman is judging your soul, this is your spot.

Navigating the Area Like a Pro
Don’t just stay in the hotel.
Step out the back door onto Brick Street and wander into Shepherd Market. It’s a tiny micro-neighborhood within Mayfair that feels like a village. There are great pubs like The Grapes or Ye Grapes (don't ask why there are two) and tiny little restaurants that have been there for decades. It’s the antithesis of the shiny, corporate London.
Actionable Insights for Your Visit:
- Book a Park View Room: It’s worth the extra spend. The wall of green outside your window is the whole point of staying here.
- Use the Residences for Families: If there are more than two of you, the townhouses on Brick Street are significantly more comfortable than cramming into a suite.
- The "Secret" Entrance: Use the side entrance if the Piccadilly traffic is too much. It’s quieter and drops you right near the elevators.
- Check the Event Calendar: They often do specific whiskey tasting nights or seasonal afternoon teas that aren't always advertised on the main booking sites.
- Walk, Don't Drive: Traffic on Piccadilly is a nightmare. You can walk to Soho in 15 minutes and Marylebone in 20.
The Athenaeum Hotel Mayfair occupies a specific niche in the London hotel scene. It’s for the person who wants the history of the Hollywood Golden Age without the stuffy dress codes of the 1920s. It’s comfortable, slightly eccentric, and undeniably British. Just remember to look up at the plants on your way in—they’re real, and they’re spectacular.
