Bueno is in Clynnog fawr, right up in the top corner of the Llyn Peninsula. It's a bungalow, so everything is on one level. The front is a bit plain, just by the road, but you've got your own enclosed garden at the back with a deck. It's a suntrap, looks over the fields.
It sleeps two. One bedroom, one wet room with a shower. The whole place was done up recently, so it's proper clean and modern. It's got a 4 Star rating. They've put grab rails in the bathroom, so it's straightforward if you have mobility issues.
The beach is a three minute walk. It's shingle, but it's quiet. For a sandy beach, Dinas Dinlle is about a ten minute drive south. The coastal path is right there if you want a walk.
You're on the edge of Snowdonia. Drive about twenty minutes and you're in the national park. Caernarfon is fifteen minutes away for shops and the castle. Caernarfon Castle is worth a look if you've not been.
Porthdinllaen is maybe half an hour up the coast. The Ty Coch Inn is there, right on the beach. It gets busy. For a day out, the Welsh Highland Railway runs from Caernarfon to Porthmadog. Glasfryn Park, ten minutes away, has go-karts and that sort of thing.
Facilities wise, there's a wood burner, a dishwasher, a washing machine, and parking. There's a BBQ in the garden. They provide bedding and towels. Up to two well-behaved dogs are allowed. There's a cot and highchair if you need one.
