Agassiz runs down Massachusetts Avenue to Harvard, along Kirkland Street to the Somerville border, and up via Beacon Street back to Porter. Down the triangle's center runs Oxford Street, a lovely residential road containing many beautiful homes as well as the Oxford Spa, a local favorite which is for sandwiches and coffee. Near the southern border of the neighborhood is Cambridge Common, a large green space with creative playgrounds, a baseball diamond, and picnicking areas. Not far away sits the popular restaurant and bar of the same name, with a live music and poetry venue, The Lizard Lounge, in its basement. In contrast to the quiet neighborhoods inside the triangle, Mass Ave provides a long row of shopping, restaurants, and other entertainment along the mile or so stretch between Porter and Harvard. The area also encompasses Lesley University, and contains student housing for both Lesley and Harvard.
