Real estate developer Keith Rubenstein is selling his luxurious Upper East Side mansion with a price tag that's just as lavish. The listing posted by Modlin Group states that the 15,000-square-foot abode, located in one of Manhattan's most elite residential blocks, is on the market for $84.5 million.

But the steep price does come with plenty gratifying perks. The palatial townhouse is six-level high, has six bedrooms, 14 bathrooms, and stunning views of the Central Park. From the entrance, a sweeping marble staircase welcomes the guests, leading to a living room with 17-foot tall ceilings. Crystal chandeliers and heavy draperies line the pink and gold living room, which houses art pieces from renowned artists.

The dining room features handmade marquetry floors just like in a Russian palace -- a nod to Rubenstein's Russian wife, former model Inga.

On the lower floors, there is a massage room, sauna, pool, and a gym. On the fifth floor is a media center, complete with a full wet bar, smoking room, and a billiard room whose walls are lined with custom red Hermes leather.

The master suite has entrances to his and hers bathroom, which has separate dressing rooms. Inga's white and gold boudoir, which she calls "Inga's world," features a freestanding tub, fireplace, a temperature-controlled closet for her furs, and a refrigerator for her makeup.

There's also a 2,500 square feet outdoor space that can be accessed by an elevator. It has a full outdoor kitchen, a Zen rock garden, and a deck that can entertain up to 100 people.

The grandiose place is also home to Rubenstein's art collection. Among many notable pieces are a pink sculpture by KAWS, a lit-up "Forever" sign by Tim Noble and Sue Webster, and other works by Jeff Koons, Jeff Koons, Rob Pruitt and Dan Colen.

Originally built in 1903, the architecture of the house takes after a Beaux-Arts style using limestone exteriors. It is described to be a home showcasing the "Gilded Age Splendor."

According to The Wall Street Journal, Rubenstein purchased the property back in 2007 for $35 million and spent at least three years extensively renovating it. The 51-year-old real estate developer stated that their reason for selling is because his youngest child will soon be leaving for college.

"We like to move every now and then," he said. "We like projects."
