I relocated from Southampton to a village about 1/2 way between Brechfa and Afan 7 years ago. I certainly wouldn’t go back. Kids are now bilingual, although the only other place in the world they speak Welsh is Patagonia. Houses are buttons, no mortage now which is also nice. Generally a bit cooler and damper than the south coast.
Jobs wise I would say that the recession hasn’t hit as hard here as it has at home.
And the welsh are a really nice welcoming bunch on the whole, you get the odd arsehole, but you get them everywhere.
