Old Hall Cottage No 1 is in Byers Green. It's a stone-built conversion, detached. The lane's quiet, no through traffic, so it's just birds and foxes going past.
It sleeps four. Two bedrooms, and two bathrooms which is handy. It's got a 4 Star rating. It's comfortable, with a woodburning stove for winter. There's another cottage on the same site, but you've got your own space.
You get a private garden area on two levels. The upper patio has a hot tub for four adults. It's for your use only. The garden looks out over fields.
There's a pub and restaurant about a quarter of a mile away. The shop is two miles, in Spennymoor.
You're well placed for getting out. Durham city centre is about 15 minutes' drive. Bishop Auckland is the same, where you've got Auckland Castle. For a day out, Beamish Museum is great. Raby Castle and the Bowes Museum are a bit further, maybe 40 minutes. You're on the edge of the Durham Dales, so Weardale and Teesdale are straight up the road.
If you want to go further, the Northumberland coast, Hadrian's Wall, and Kielder are all within an hour and a half. The Lake District is about two hours.
Facilities: parking right there, WiFi, TV, dishwasher, washing machine. Bedding and towels are included. There's a cot and highchair if you need them. One well-behaved dog is allowed.
For planning days out, the This is Durham site is useful. For walks and cycling locally, the Durham County Council countryside pages have maps.
