Gareth is in Milton, just outside Pembroke. It's one of a pair of cottages, semi-detached, with its own enclosed garden at the back. You're in the Pembrokeshire Coast National Park, and Carew Castle is a few minutes' walk down the lane.
It sleeps five. Three bedrooms, one bathroom. It's a 3 Star place. That means it's clean and comfortable, not luxurious. The stairs are a bit steep and narrow, as you'd expect.
There's a local shop about half a mile away. The nearest pub is a mile, in Milton. It's a proper village pub.
For beaches, you're well placed. Manorbier is about seven miles, with its castle. Tenby and Saundersfoot are around twelve miles. Lots of options depending on the wind direction.
The cottage itself has what you need. Washing machine, dishwasher, TV. Parking for one car right outside. Bedding and towels are included. You can bring one dog. There's a cot and highchair if needed.
If you're planning walks or days out, the Pembrokeshire Coast National Park site is useful. For local history, Carew Castle is just down the road.
