There’s nothing like soft morning light that quietly peeks through the windows on a beautiful summer morning in New England… We’re loving this scene from our Penthouse Queen Studio featuring coastal blues and an abundance of natural light.

Warm breezy mornings and Getty bagels by the water… Life is good.

So, what IS an apart-hotel?? The apart-hotel experience offers a bit more than a traditional hotel room with ten of our rooms featuring fully-equipped kitchens and ensuite bathrooms with washers and dryers. To allow for independence during your stay, we don’t have a team on-site, but are never more than 10 minutes away if you need anything—whether it's help getting into your room or a text with personalized recommendations for the best local boat ride and our favorite spots for dinner!

Guests who book stays with us will receive detailed instructions for self check-ins 24 hours prior to their arrival. Once you arrive and access your apartment, we are available by phone 24/7.
