Seashells is a bungalow in Lowestoft. It's on a normal, quiet residential street. You can walk to the beach in about five minutes.
It sleeps four. Two bedrooms and one bathroom. The main bedroom has a Superking bed that splits into two singles if you need it. The bathroom has a shower over the bath. It's got a 4 Star rating, which means it's well-equipped and comfortable.
It's a bungalow, so everything's on one level. That's handy if stairs are a problem. There's a small conservatory off the kitchen and an enclosed garden out the back. It's secure for dogs.
You can have up to two pets. Bedding and towels are included. There's parking on the drive. The kitchen has a dishwasher and there's WiFi.
For the beach, I'd go north towards Gunton or south towards Kessingland. They're quieter and dog-friendly all year. Lowestoft itself is a proper seaside town. It's got the usual things: fish and chips, amusements, a pier.
If you want a walk, the Suffolk Coast Path runs right past. Southwold is about twenty minutes' drive up the coast. The National Trust looks after Dunwich Heath and Minsmere, which are both within half an hour. The Norfolk Broads are about the same distance inland if you fancy a boat trip.
That's about it. It's a comfortable place to come back to after a day out.
