For anything not covered in the Airbnb booking page just send me some words, then I'll get back to you as soon as I can. Please don't just knock on my front door. Really.
The Market House
You've either got GPS, Google, or some other app. So why do you need my help? Anyway, once you find HR6 9EA, then you'll be here. Market House and the barn is literally there. Right by the New Inn and historic market square. If you are using a paper map then I respect you hugely. It's pretty much midway between Kington and Leominster (which is pronounced LEM-ster, just in case you didn't know.) You'll figure it out.
