About this home

Set in leafy Riverside, midway between Harvard and Central Squares, this inviting raised 1st floor unit provides comfortable gathering and private spaces with great amenities. The open living/dining space featuring oak floors and good ceiling height is enhanced by a wide, southwest-facing window bay. The granite and stainless kitchen, which overlooks the property’s fenced patio and garden area, offers generous storage and counterspace, including a 3-seat peninsula. The spacious primary suite, serenely set at the rear of the property, includes a deep walk-in closet and tiled bath with a window and walk-in shower. The second bedroom accommodates a queen-sized bed and has a wide closet, and there is a second bath, also with a window and walk-in shower. Central air, in-unit laundry, basement storage, and off-street parking. So much good stuff in such a great spot! (Harvard Sq & Charles River 0.3mi; Central Sq T 0.4mi; HBS 0.6mi)
