Wales in heatwave

We arrive in a heatwave - 29C-for our holiday in Wales and we are based in a 18th century coaching inn, the Bear, Crickhowell.
The building has been welcoming guests since 1432.

Its our first ecperience of a heatwave south of the border and i dont like it. .Its   scary . We have two more days of it. And of course there is no airconditiining
