BY NOW we all know that Meghan Markle’s New York baby shower was hosted by Serena Williams and Genevieve Hillis, for 20 of the Duchess’s closest friends  including Amal Clooney, Gayle King, and Suits co-star Abigail Spencer. Luxury lovers will also note that the celebrations took place in Serena Williams' room, the Grand Penthouse at The Mark Hotel. So let’s take a look at what has been described as the world’s most expensive Suite and see just how babylicious it really is.

Opened in 2009 and discreetly positioned on Madison Avenue and 77th Street, The Mark is a haven for Upper East Siders who shop and for celebrities looking for a low key stay without the glitz. That doesn’t mean there is no glamour, The Mark is one of the most sophisticated and opulent hotels in the city, it just has too much good taste to be showy. Interiors were designed by Jacques Granges (known for his boho-meets-high end style), with bespoke objets d’art, furniture and lighting fixtures from the late Karl Lagerfeld,Todd Eberle, Ron Arad, Vladimir Kagan, and Mattia Bonetti among others.  Granges once said “I don’t like anything too shiny, too gold-y, too bling-bling. I love the balance between the very simple and the very sophisticated.”

The aesthetic is appreciated; this is the place where people go for cocktails before the Met gala and where the true fashion insiders stay during New York Fashion week. Owner 2009, Izak Senbahar (of the Alexico Group) once told The New York Times the hotel is where “fashion people and celebrities feel liberated”,  because they are pampered but not stared at.

The Grand Penthouse is considered one of the largest and most expensive penthouses in the US., costing $75,000 a night and set on the top two floors of the hotel. The palatial penthouse is a vast 12,000 square-feet.

There are five bedrooms, six bathrooms, two powder rooms, a chef’s kitchen, four fireplaces, a library lounge, and a private elevator, The living room with a grand piano and 26-foot ceilings, is located in the corner tower of the building and is large enough to be converted into a full-sized grand ballroom.

The Mark penthouse boasts its own Conservatory, Library Lounge, stately Dining Room and a stunning private rooftop terrace with an outdoor dining & entertaining area and breath-taking views of the city. And if that’s not enough there is a massive rooftop terrace overlooking Central Park.

And who catered for Meghan's shower? Could food perhaps have come from the hotel’s Michelin-starred restaurant by Jean-Georges Vongerichten. We hope so. All the rooms and suites have special touches: for example Ladurée macarons are left on the bedside tables at night and guests can have everything from caviar to chocolate chip soufflé delivered to their rooms around the clock. But frankly that means nothing to the people who stay here at the penthouse. “We have heads of state, very wealthy business people, and celebrities renting this space, and they could not care less about a Bentley at their disposal 24/7,” The Mark’s GM told Bloomberg.com. Basically what a penthouse guest wants, a penthouse guest gets - whatever it may be. Personal service writ large.

So what would be the ultimate present for the baby who will have everything? Why a lifetime of visits to this superb suite of course. Book that baby in!
