Driftwood is on a chalet park in Mundesley. It's detached. The park is well looked after, the chalets are traditional. You're a few minutes' walk from the beach, which is a nice wide sandy one. Locals use it a lot.
It sleeps four, in two bedrooms. One bathroom with a shower. The rating is 3 Star, so it's clean and comfortable but it's not a hotel. Everything is on the ground floor, which is good if stairs are a problem. The entrance is wheelchair accessible.
The space is open plan. There's a TV, and Wi-Fi, but the Wi-Fi is shared with the park so it's fine for checking things but maybe not for streaming films. Bedding and towels are included. Parking is on site.
The beach is the main thing. It's a quarter of a mile away, so you can easily go back and forth. There's a local pub and restaurant about a mile away. Fishing is available locally, and there's a golf course too.
If you want to explore, Cromer is a classic seaside town with a pier and amusements. The North Norfolk Railway runs from there. For a longer trip, you can get the coast hopper bus all along the coast to places like Wells-next-the-Sea and Hunstanton.
For nature, the RSPB at Cley Marshes is good for birdwatching. The National Trust looks after several big estates nearby like Blickling and Felbrigg. The National Trust Norfolk page has details. The Broads are about a 45 minute drive.
Sorry, no pets.
