This is the Old Stable, it's in Bethel. It's a detached cottage, so no one attached to the sides. It was a stable originally, hence the name. You get the garden to yourselves, it's enclosed.
It sleeps four. Two bedrooms, both doubles. One bathroom with a shower over the bath. There are no stairs at all, everything is on one level, which is good if stairs are a problem.
It's got a 4 Star rating. It's warm and clean. There's an open stone fireplace in the living room, but it's not for use. Heating is electric. There's a Smart TV, WiFi, a washing machine, and bedding and towels are included. Parking is right outside.
The location is rural but not isolated. You're about fifteen minutes drive from the edge of the Snowdonia National Park. Llanberis is close by for the Snowdon Mountain Railway and Llyn Padarn. Caernarfon with its castle is about twenty minutes away. The coast and Anglesey are within half an hour.
If you've got children, Greenwoods Family Park is five minutes down the road. There's local fishing and horse riding. No pets, sorry.
