Enjoy the tranquility of the South End's best kept secret; Montgomery Park. This gated and locked park is accessible only by Park abutters and offers residents the feeling of being in the country while living in the heart of the South End. Owners at 20 Dartmouth can leave their garden-level family room and out to their private terrace before arriving in the Park. The Park has a selection of seating areas with wrought iron tables, historic gas lamps as well as the working fountain. Gardeners will delight in this luxury. This charming 5+ bedroom single family townhouse offers period moldings and door casings along with modern updates including two beautiful kitchens perfect for entertaining both on the parlor and in the garden. The street level entrance has been built out with a mudroom with cheery floor tile and cubbies. Each of the five bedrooms is large with spectacular closet space. At the top of the building, through a head house, awaits a private roof deck with sweeping city views.
