7. Only one Remaining Duplex in The South Tower Was Part of The San Remo’s Original Design

While most of The San Remo’s original duplexes have been lost to time, the 7,000-square-feet South Tower Penthouse is the only one remaining from the building’s original design. According to 6sqft, it has acquired a portion of the tower’s mechanical and storage space, thereby elevating it to the next level as a “triplex penthouse.”

It features 17-rooms, multiple terraces and 360-degree views from all floors. It was most recently owned by actress Demi Moore until she sold it to an entity called M2 Trust for a hefty sum of $45 million — still, that’s $30 million less than her original asking price of $75 million.
