About this home

Seize the opportunity to see this unique two bedroom first floor condo located on a quiet tree-lined street. A stunning wood foyer entrance with closet gives room for seating and greeting. The living room has stately columns and original wood window/trim framing connecting to a formal dining room with a gorgeous New-England-style built-in china cabinet. The full bathroom with tub/shower has tiled walls and flooring. Bedrooms have wood flooring and closets. Natural woodwork shines in this condo. An expansive shared yard and off-street parking for 2 cars has great space for parties and play time. Serene views from the exclusive use front and back porch areas add to the charm. An enormous amount of private storage and laundry in the basement offers expansion potential. Updates include removing the chimney in 2015, front porch replacement in 2014, water line replacement in 2013, roof replaced in 2011 and blown-in insulation to lower utility costs. The first floor has a bonus mini split in the dining room for more heating and A/C. Watertown has wonderful public transportation options and just opened the first US-recognized net-zero energy and LEED 4.1 Platinum status high school. Other amenities include the Charles River community path for nature walks, a wonderful library, a variety of shops, restaurants, the farmers market, Urgent Care, Watertown Boys and Girls Club, and Sister Thrift - it's such a great place to be. This condo is also only 2 -3 blocks from Belmont and its dining, shops and cafes on Belmont St and Trapelo Road so don't miss this one!
