Trebisken is in Porthtowan, about a five minute walk from the beach. It's an eco-house, detached. You have your own garden and a parking space.
It sleeps up to six people in three bedrooms. There are two bathrooms, which helps when everyone's getting ready. It's got a 4 Star rating. It's comfortable and well-equipped, not especially fancy.
The village is small. There's a shop, a couple of cafes, a restaurant, and a beach bar that does food. The beach itself is good for surfing.
You can walk to Chapel Porth beach from here at low tide. The South West Coast Path runs right through the village. You can head west towards Portreath or east towards St Agnes. The views are very good.
If you want to drive, you're close to the A30 so it's easy to get around. St Agnes is about ten minutes away. Newquay is roughly twenty minutes. The National Trust Cornwall page has details on local places like Godrevy or the Minack Theatre, which is about an hour's drive. The Eden Project is around forty minutes.
For facilities, it has what you'd expect: WiFi, a washing machine, dishwasher, and bedding and towels are included. You can bring one well-behaved dog.
