Meadow Cottage is in Tregeseal, near St Just. It's detached, so you won't have anyone through the wall. The garden is enclosed, which is handy if you're bringing a dog.
It sleeps three, in two bedrooms, with one bathroom. There's a woodburning stove in the living area, which is open plan. You get bedding and towels.
There's a shop and a pub half a mile away. The coast path is close, about two miles to a beach. St Just itself has a few things, it's a small town.
The area is part of the Cornish Mining World Heritage site. Geevor Tin Mine is worth a look if that interests you. The landscape is full of old engine houses. The Tregeseal Stone Circle is on the moorland behind the cottage.
Within half an hour's drive you can get to Sennen Cove for surfing, the Minack Theatre near Porthcurno, and St Michael's Mount at Marazion. Penzance has the usual town things. The road to Land's End is busy in summer.
For facilities, it's got WiFi, a TV, a washing machine, and a dishwasher. One well-behaved dog is allowed. There's parking.
