Cerrig Sais is in Rhosgadfan, above Caernarfon. It's a single-storey house, so it's all on one level which is handy. The view is the main thing. You get the whole of Anglesey and Caernarfon Castle from the big windows, especially at sunset.
It sleeps eight. Four bedrooms, two bathrooms. The 5 Star rating means it's well kept and has everything you'd need. It's on its own track, so it's quiet. You're not overlooked.
There's a hot tub on the patio. The garden is yours. Inside, there's a washing machine, dishwasher, WiFi, and TV. Bedding and towels are included. We've got a cot and highchair if you need them. Parking for a couple of cars right outside.
You're about five miles from the nearest beach, like Dinas Dinlle. Caernarfon is three and a half miles down the hill. That's where you'll find the shops, the castle, and places to eat. The local pub that does food is about two and a half miles away.
For things to do, you're well placed. The whole of the Menai Strait, Snowdonia, and the Llyn Peninsula are within a half hour drive. Good for walking, the coast, or just pottering around historic sites.
