This is Knights Rest. It's in Conwy town, right by one of the old towers on the town walls. You can see the castle from the front. It takes about five minutes to walk down to the quay or the main streets.
It's a new build, one of three in a terrace. Sleeps four, two bedrooms, one bathroom. It's got a 4 Star rating. It's modern inside, everything works, and it's kept very clean. The stairs are fine.
Downstairs is open plan. There's a small, enclosed patio out the back with a table and chairs. You can sit out there if the weather's nice. On-street parking is right outside the door.
You've got a dishwasher, washing machine, TV, and WiFi. Bedding and towels are included. There's a cot and highchair if you need them. No pets, sorry.
For days out, you're right on the edge of Snowdonia. It's about a twenty minute drive to get into the proper mountains. The A55 is close if you want to head along the coast. Bodnant Garden is a short drive away, it's a National Trust place and very popular.
