Book this place. You won't regret it.
It's magical.
You are staying with a family. You are part of the family.
You get the true British experience.
This is a real airbnb. How airbnb used to be. How airbnb should be.
Very personal. More like how I expect Couchsurfing to be.
Do not think too much. Book it. ;-)
... and send my best regards to Pat and Josh.
