Badgers Loft is in Sennen Cove. It's a studio apartment up in the eaves, so it just sleeps two. The views out over the sea are good, especially for a sunset.
It's a 4 Star place. That means it's modern and well done inside. The space is open-plan, so the bed is at one end. The kitchen is small but has what you need. There's a wood burner for cooler evenings.
You're right on the coast. The famous white sand beach and the lifeboat station are literally a minute's walk away. You can hear the sea. The local pub is close. The village shop is handy for basics.
The stairs to get up to the Loft are quite steep and narrow. It's an old building. Something to be aware of.
Facilities: WiFi, towels and bedding are included. There's a small patio area. Sorry, no pets.
For things to do, you're well placed. The South West Coast Path runs right through. Lands End is a short drive or a decent walk. The Minack Theatre is about ten minutes by car. St Ives is a bit further, maybe 25 minutes, but the open-top bus goes there from the cove which is a nice trip.
