About This Home

21 Stone Ave #21

A rare opportunity to own a home just steps from Union Square, one of Somerville’s most vibrant and historic destinations, located only a quarter mile from the Green Line station. Nestled on a quiet side street at the base of Prospect Hill, where the first American flag was raised in 1776, 21 Stone combines neighborhood charm with urban convenience. From the private entry, you’re welcomed into an open light-filled living and dining space, where tall ceilings and large windows set a warm, inviting tone. The kitchen is both stylish and functional, with a southeast facing breakfast nook that captures the morning light. Additional perks include private laundry and storage in the basement, an off-street parking space, and shared patio ideal for outdoor gatherings. With award winning restaurants, cafés, and markets just around the corner, this home offers modern comfort rooted in the rich history and energy of Union Square.
