CONCIERGE SERVICES You like your independence, but sometimes you need an insider. We provide personal concierge services for all our guests during their stay with us. Looking for the best sushi in Portsmouth? Want to know where to rent kayaks to explore our islands? Want particular groceries delivered to your studio? Need information about day trips to Portland, Boston, or Newburyport? Our local concierge has you covered. NEW CASTLE & THE AREA Off the coast of Portsmouth, New Castle is New Hampshire’s smallest, easternmost town comprised entirely of islands. A quiet coastal town of just 968 residents, New Castle offers historic sites, lighthouses, beaches and outdoor activities within the serenity of a small New England village. We're just a scenic, five-minute drive to lively downtown Portsmouth – with extensive shopping, nightlife, entertainment and over fifty renowned restaurants. Directly across the banks of the Piscataqua river you will find yourself in Maine’s southernmost town of Kittery. An eight-minute drive from New Castle, this seaside town is full of eclectic boutiques, art galleries, and hip restaurants. Fresh-caught Maine lobster is a must during your visit!A UNIQUE LODGING EXPERIENCE. Our studio apartment-style rooms feature fully-equipped kitchens and in-room laundry.
