This is Castle Street in Llanystumdwy. It's a terrace house, right in the village. You can see the sea from the back garden.
It sleeps four people. Two bedrooms and one bathroom. It's got a 4 Star rating. It's comfortable and everything works. The stairs are a standard sort of steep, like most houses round here.
You're really close to the coast. It's about a two minute walk down to the beach. You do need to keep an eye on kids and dogs there, it's just common sense.
Criccieth is just down the road. The castle is there, and a golf course. The village itself has a shop, a pub, and a restaurant about fifty yards away. They're handy.
You can get up into Snowdonia from here. The Ffestiniog Railway station is in Porthmadog, which is about a ten minute drive. That takes you up into the hills. Portmeirion is also nearby, maybe fifteen minutes by car.
Further afield, within half an hour or so, you've got Caernarfon Castle, Harlech Castle, and the foot of Snowdon. Beddgelert is in that direction too.
For facilities, it's got what you'd expect. Washing machine, TV, WiFi. Bedding and towels are included. There's a cot and a highchair if you need them. One well-behaved dog is allowed.
