About this home

Perched on the third floor atop Observatory Hill, this bright 2 BD, 1 BA floor-through residence blends comfort and modern convenience in a prime location. Sweeping sunset views over Cambridge and Danehy Park are paired with a private tree-top deck, hardwood floors, efficient AC and in-unit laundry. The open layout flows from a corner living room with bay window and dual exposures into the dining area and expansive kitchen with breakfast bar and stainless appliances. Both of the spacious, south-facing bedrooms are bathed in natural light. Recent updates include 2024 mini-split systems, replacement windows, exterior insulation and refreshed 2026 bathroom. Basement storage and off-street parking add everyday ease. Ideally positioned between Harvard Sq, Porter Sq, Fresh Pond, and Huron Village, just moments from local favorites like Imagine and Formaggio Kitchen. Convenient access to bus lines and Red Line service offers easy connectivity across Cambridge and beyond.
