Welcome to the crown jewel of 20 Putnam Street. This Philadelphia-style duplex lives like a private single-family, with soaring ceilings, luminous interiors, and exclusive access to a beautifully landscaped fenced yard. The main level features open-concept living and dining anchored by a Bosch-appointed kitchen with Fisher & Paykel two-drawer dishwasher, plus two spacious bedrooms and a full guest bath. Upstairs, the entire second floor is devoted to a serene primary suite with walk-in closet, double vanity, and spa-like shower. Below, a private laundry room and versatile bonus space offer room to stretch out. Radiant heated bathroom floors, all-electric systems, one-car tandem parking, and private storage complete the offering. The location near Union Square, the Green Line, and Bow Market puts you close to Somerville’s most vibrant restaurants and cafes. With its classic layout, generous scale, and private yard, Unit 1 offers comfort, character, and unbeatable access.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
