Gwynfa is a bungalow in Rhyl. It's detached on a quiet street, so it's peaceful but you're not far from things. There's parking right outside and the garden's all yours.
It sleeps four. There are two bedrooms on the ground floor. One has a double bed, the other has a zip-and-link bed that can be either a king-size or two singles. One bathroom with a shower over the bath. It's got a 3 Star rating, which means it's clean, comfortable and everything works, but it's not luxury. The entrance and the main rooms are wheelchair accessible.
The living room and kitchen are just what you'd expect. There's a TV, WiFi, a washing machine and a dishwasher. Bedding and towels are included. You can bring one dog.
Rhyl Beach and the promenade are about two miles away. It's a classic North Wales seaside strip. The SC2 centre on the prom has an indoor water park and an outdoor splash area. There's a local pub and a golf course nearby.
Within a half hour drive you've got a few options. Prestatyn Beach is just along the coast. Bodelwyddan Castle is about twenty minutes inland. If you head west along the coast, you reach the start of the National Trust land around the Great Orme. For a bigger day out, Snowdonia National Park is about 40 minutes' drive.
