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.
