Number 4 is in Llandeilo town itself. You park right outside on the street, which is usually fine. It's a terraced house over two floors.
It sleeps four. Two bedrooms upstairs, one with twin beds and one with a double. One bathroom. It's got a 3 Star rating from Visit Wales, which means it's a clean, comfortable base.
You're about fifty yards from a couple of pubs and a shop, so you don't have to drive everywhere. There's a small patio out the back with a table and chairs. It looks down towards the river Towy.
The kitchen has what you need. Oven, fridge, microwave, washing machine. There's WiFi and a TV. All bedding and towels are included.
You can have up to two dogs. Just so you know, the stairs are a typical cottage staircase, so they're a bit steeper than modern ones.
Location wise, you're right on the edge of the Brecon Beacons. For gardens, the National Botanic Gardens and Aberglasney are maybe a ten minute drive away. Carreg Cennen Castle is about fifteen minutes in the car. It's a proper ruin on a cliff. Good for a walk.
The coast, like Pendine Sands, is about forty-five minutes to an hour's drive depending on traffic. Carmarthen is twenty minutes away for bigger shops.
Some useful links if you're planning: Dinefwr (National Trust) and the Brecon Beacons National Park site.
