It's a standard three bedroom terrace house. Sleeps five. One bathroom upstairs, with a walk-in shower. There's a toilet in the outbuilding in the garden too, which is handy if you've got kids playing outside. The garden is enclosed and gets the sun.
The house has a 4 Star rating. It's comfortable and has what you need. WiFi, washing machine, dishwasher. Parking for one car on the drive.
You can take up to two dogs. The garden is fully fenced.
Conwy itself is the main thing. The castle and town walls are incredible. The quay is nice for a wander. The smallest house in Britain is there, it's just a curiosity really. Conwy Morfa beach is about a mile and a half away. It's a big sandy beach, good for dogs and kids.
Within half an hour you can be in Snowdonia. Betws-y-Coed is about twenty minutes drive. For bigger mountains, the Ogwen Valley or Capel Curig are roughly thirty minutes. The North Wales coastal path runs right past the town.
