The Den is in Penysarn, which is a small village at the bottom of Parys Mountain. It's one of three apartments around a shared courtyard, behind Ty Copr shop. The courtyard is enclosed if you've got dogs.
It sleeps four. Two bedrooms and one bathroom with a shower. It's got a 4 Star rating. The layout is all open plan downstairs.
There's a village shop and post office about 50 yards away for basics. The local pub is in Llanallgo, about three miles away. For a bigger supermarket, you'd drive to Amlwch, which is only a few minutes. It's a port town with a nice little harbour.
The beach at Traeth Lligwy is about four and a half miles. It's a lovely sandy beach. The coastal path is right there too. You can often see seals, and sometimes dolphins, from the headlands. Boat trips for fishing or puffin watching leave from nearby places like Moelfre.
If you want to go inland, Snowdonia is about a 30 minute drive. You can be walking up in the hills quite quickly.
In the apartment there's a woodburning stove, a TV, WiFi, and a washing machine. Bedding and towels are included. You can bring up to two dogs. There's parking on site.
