I've just come back from a weekend touring mid Wales. We used Riverbank Bed and Breakfast on the bank of the River Irfon in Llanwrtyd Wells. Excellent accommodation with secure indoor parking for the bikes and a great breakfast. Really well positioned for some great local rides, especially the Devils Staircase. Close enough to the Brecons to the south and Snowdonia to the north. Makes a great base. Really biker friendly, would recommend.
And I forgot to say that in addition to a pub with a brewery, which of course is of utmost importance (!) there’s also Mid Wales Motorrad in the old mill on the other side of the road. I’ve always found them to be very helpful
