Welcome to 309 Riverside Street, a charming waterfront residence located on Blue Bill Cove in Island Park-Portsmouth. From the moment you enter through the front door, this two-bedroom, two-full bath home has unobstructed views of the water. The charming covered porch opens to a home office, fully renovated kitchen with granite countertops & stainless appliances and bright open-concept dining & living areas. Enjoy waterfront dining or your morning coffee on the large deck which has stairs down to a patio and direct water access. The upper level of the home has two bedrooms including the oversized primary bedroom with large windows facing the water, a sitting area & large walk-in closet. A full bathroom with laundry and guest bedroom round out the second level of the home. Additional features include Velux "smart" skylights, a gas-fired Navien heating system and central vacuum. Lower level storage is ideally laid out to hold all of your summer gear as well as year-round storage. The yard is perfectly low maintenance with perennial plantings and hardscape areas. All that is left to do is drop your bags and head to out to enjoy kayaking around Spectacle Island, a barbeque on your back deck or take in some live music at Sunset Cove or one of the many great restaurants Island Park has to offer!
