Great Island Inn

In the very center of New Castle, this boutique apartment hotel sits in a quiet New England island town just steps from Portsmouth Harbor Lighthouse and Fort Constitution. Fort McClary State Park, Fort Stark and Wentworth by the Sea Golf Club are minutes away, and lively downtown Portsmouth is a scenic five-minute drive.

Six individually decorated studio apartment-style rooms blend simple coastal touches with practical comforts. Rooms feature pillowtop beds, heated floors, flat-screen TVs, private furnished patios, fully equipped kitchens and in-room laundry — perfect for night, week or month stays.

Enjoy a garden with a picnic area and barbecue grills, bike parking and concierge service. Self-parking (fees apply), luggage storage and express check-in/out keep things easy — wake up to sea-breeze mornings and step out for a coastal walk.

Complimentary wireless internet across the property, plus express check-in/checkout and luggage storage. The apartment-style layout and in-room laundry make it a practical home base for extended stays or work trips.

Kitchens are outfitted with refrigerators, ovens and microwaves for self-catering, and the picnic and BBQ areas invite casual outdoor meals. A short drive delivers Portsmouth’s dining scene with over fifty restaurants nearby.
