The Great South Barn is in Gimingham. It's a converted barn, one of a pair. You can book it with the other barns here if you have a big group.
It sleeps twelve people. Six bedrooms, four bathrooms. Three of those are en-suite. It's a 5 Star place, so it's well finished and has good kit. It's open plan downstairs, so it works for everyone being together.
The village is quiet. There's a shop and a pub about a mile away. The coast is under two miles. Mundesley beach is sandy and usually not too packed. Cromer is about six miles up the coast if you want a proper pier and promenade.
You're about half an hour from the Broads at Wroxham, if you fancy a boat trip. The National Trust at Sheringham Park is good for walks. Felbrigg Hall is another National Trust place nearby.
For facilities: there's parking, a washing machine, a dishwasher, a BBQ, and an enclosed garden. WiFi and TV are there. Towels and bedding are included. You can bring two dogs.
