This is Sea View, in Dinas Dinlle. It's a first floor apartment in a building right on the seafront. The name is accurate, you get a full view of the sea and the beach from the living room.
It sleeps eight people in four bedrooms, with two bathrooms. It has a 4 Star rating. It's spacious, with an open-plan kitchen and living area so everyone can be together. The sofas face the windows so you can just sit and watch the water.
You're about a minute's walk from the beach. It's a big, sandy beach, good for walking and playing. There's a slope down to it. The local beach café is decent. The building has a shared patio area with seating if you want to sit outside.
Dinas Dinlle is quiet. There's a historic hillfort right there on the hill if you fancy a short, steep walk with a good view. The Welsh Air Museum is just along the road.
Caernarfon is about a 15 minute drive. You've got the castle there, which is a UNESCO World Heritage site, and plenty of shops. The Snowdonia National Park starts not far from here. You can drive into the mountains in under half an hour. The drive to the foot of Snowdon itself is about 30 minutes.
For a day out, Zip World is within 30 minutes, and so are the Llechwedd Slate Caverns. The coast road south takes you to places like Criccieth.
Inside, it's got what you'd need: a washing machine, dishwasher, WiFi, TV. Bedding and towels are included. There's a cot and highchair if needed. On-site parking. You can bring up to two dogs.
