Castlemans Stables West is in Sedlescombe. It's a converted stable, one of a pair. You've got your own bit of garden, and the fields are right there.
It sleeps four. Two bedrooms, two bathrooms. It's a 4 Star, so it's comfortable and well equipped. It's a good size for two couples or a small family. Pets are allowed, up to two dogs.
The place is set up so you're not overlooked. There's a woodburner for cooler nights, and a BBQ outside. All the basics are covered: parking, washing machine, wifi, bedding and towels are included.
Sedlescombe is quiet. The village pub, The Queens Head, is a short walk away. They do food and are dog friendly. The Sedlescombe Vineyard is about a mile away for tours and tasting.
Battle is a ten minute drive. It's got the abbey and High Street shops. For a bigger day out, Hastings is about fifteen minutes by car. The seafront and the old town are worth a look.
For planning walks or visits, the National Trust Sussex page is useful, and 1066 Country covers the local area.
