Wheal Trenwith Cottage is in St Ives. It's detached, in a quiet bit just up the hill from the town. You can walk down to the harbour and beaches in about five minutes, which is handy. There's parking right there so you don't have to worry about finding a space.
It sleeps four, in two bedrooms. One bathroom. It's got a 4 Star rating, so it's comfortable and well kitted out.
The layout is a bit different. The bedrooms and a separate toilet are on the ground floor. Then the living area, kitchen, and main bathroom are upstairs. That's where you get the views. There are doors out to a private balcony that looks out towards the sea. It's a good spot for a coffee. The stairs inside are a normal flight, nothing tricky.
You've got everything you'd need. Dishwasher, washing machine, TV, WiFi. Bedding and towels are included. We can provide a cot and highchair if you need them. No pets, sorry.
Honestly, the best bit is that you can leave the car and just walk. There are three main beaches within easy reach. Porthmeor for surfing, Porthminster for sand and cafes, and the harbour beach. The town is all little streets with shops and galleries. The Tate St Ives is down there if you're interested.
If you do drive, the coastal path is right there for walks. You can get the scenic train to Carbis Bay and Lelant, which is nice. For a day out, Trengwainton Garden near Penzance is about twenty minutes by car, and the Minack Theatre is about forty minutes. The whole Penwith peninsula is good for exploring.
