Cosy Cwtch is in Hay on Wye. It's a two bedroom house for four people. It's got a 5 Star rating, which means it's well-finished and everything works.
The layout is simple. Downstairs is a living room, a dining room, and a kitchen that has what you need. Upstairs are the two bedrooms and one bathroom. The bathroom has both a shower cubicle and a bath. Outside the back is a small, enclosed courtyard. It's private and gets the sun in the morning.
You're right in the middle of town, so you can walk to everything. The famous bookshops are just around the corner. The local shops and pubs are good. If you've got a dog, there's a path by the river Wye that's easy to get to.
The Brecon Beacons are about a twenty minute drive away for proper walks. Brecon Beacons National Park has all the route information. The Black Mountains are a bit closer, maybe fifteen minutes.
Facilities wise: there's a washing machine, WiFi, and the bedding and towels are included. You can bring up to two dogs. There's parking for one car on the street outside.
