Great Island Inn Reviews

“We stayed in apartment number 5 and had a great view of the water and perfect breeze. Everything was very clean the snacks and drinks were nice to have in a pinch! Make sure to get breakfast at the Islander cafe!”

“Super small studio apartment. Clean, inviting design. Feels new. Super clean. Very comfortable bed and pillows. Super cute area with historic homes with beautiful gardens and less than 10 minute walk to a beautiful beach and a nice park beyond that. Classic New England feel. 10 minutes to downtown Portsmouth. Cafe next door has really nice breakfast options. Highly recommended for an individual or couple.”
