This is 2 Salle Cottage in Tuckenhay. It's part of a group of converted mill buildings by Bow Creek, which is a little inlet off the River Dart.
It sleeps six people. There are three bedrooms and two bathrooms, which is useful. The rating is 4 Star, so it's comfortable and well-equipped. You can bring one dog.
The cottage has its own garden. Inside, it's got a woodburning stove, a dishwasher, and a washing machine. Bedding is included, and there's a cot and highchair if you need them. Parking is on site.
Being part of the mill complex means you get to use the leisure facilities. There are two indoor pools and one outdoor pool, plus a games room and a sauna. There's also a kids' play area. It's a short walk from the cottage, across a footbridge.
There's a pub you can walk to along the creek. For a shop, you'd need to drive to Totnes, which is about three miles.
Location-wise, you're about five miles from Dartmouth. The coast at Blackpool Sands is about a 20-minute drive. For surfing, Bantham beach is about half an hour away. Dartmoor is within easy reach for walking.
