Two-and-a-half years ago and at age 29, product designer Sara Duval took the plunge into homeownership by purchasing this 400-ish-square-foot studio apartment in Manhattan. (For those who are curious, she does a great job of breaking down the financials of this purchase on her TikTok account.) Located in a building from 1920, the apartment might be 125-years-old, but Sara's created a warm, personal, and modern home.
