Inside Léman Manhattan Preparatory School, the New York City boarding school that costs more than Harvard

Manhattan has the largest population density of any city in the US, and its K-12 schools serve more than 1 million students.

Yet, there is only one boarding school on the entire island: Léman Manhattan Preparatory School. Léman is an elite private school located in the southernmost part of the city. It educates more than 700 students in grades pre-kindergarten through 12, and is home to about 100 students who board from all over the world.

Its price tag for tuition, room, and board is $79,000 a year, nearly $16,000 more than Harvard. And boarding students enjoy perks likely unheard of even at the collegiate level, like full-service concierge and luxury apartment buildings.

So when Léman invited Business Insider to take a tour of the school, we jumped at the opportunity to see just how unique the facilities and course offerings really are. Paige Murphy, the director of admissions at Léman, was our tour guide for the day.

Here's what it's like to attend Léman as a high school boarding student.

We arrived in the Financial District of New York City on a sunny February day to start our tour of Léman and its surrounding neighborhood. The first thing we saw was popular tourist attraction Charging Bull, the 7,000 pound bronze sculpture and Wall Street icon.

Turning the corner, we found the Léman entrance on the quieter Morris Street. Léman opened its doors in 2005 starting with just 54 students. Twelve years later it has more than 700 students, about 100 of whom are boarders.

"You think of the American boarding school experience and you think more New England, rural, fields, not in the heart of the biggest capital city and financial center of the world," head of admissions Paige Murphy said.

Rural it is not. The Financial District (FiDi) is a bustling part of the city, especially during work hours. Goldman Sachs, The New York Stock Exchange, and Deutsche Bank are just some of the financial companies with offices in FiDi.

Murphy said students and families attracted to Léman tend to be those who want an urban environment and access to business internships and the city's top arts programs, that the school can help provide.

Léman recently added squash to its sports offerings. "Squash is very hot right now," Murphy said.

"It's really competitive for university admissions. A lot of the top tier schools, the Ivy Leagues, are looking for squash players," Murphy continued. Léman currently has three students nationally ranked in the top 50 for junior squash players.
