Oak Lodge is in Llanteg, Pembrokeshire. It's a wooden lodge on an estate with a few other properties. You get your own balcony and bit of garden, but there are some shared spaces too.
It sleeps four. Two bedrooms and a bathroom, all on the ground floor. One bedroom has a double bed and a door that opens straight out to the field behind. The other has two singles. The stairs inside go up to the main living space, which is open plan. There's a sliding door up there that opens onto a small balcony. You can see a bit of the sea from there on a clear day.
The place has a 3 Star rating. It's comfortable and clean. The shared areas on the estate include a field, some woodland, an orchard, and a tennis court.
You're about a mile and a half from the coast. Amroth beach is the closest. Further along you've got Tenby and Saundersfoot. Good for walking, swimming, or just sitting on the sand.
Folly Farm is a ten minute drive if you've got kids. It's a zoo and an adventure park. For a quieter walk, Colby Woodland Garden is nice.
There's a washing machine and a TV. WiFi is included. Bedding and towels are provided. You can bring one well-behaved dog. Parking is right outside the lodge.
For planning, the Pembrokeshire Coast National Park site is useful, and Visit Wales has good general info.
