Welsh Long Distance Walk - accommodation query

[Walking Englishman]

Has anyone walked in the centre of Wales? I am walking my own route from north coast to south coast in May and looking for accommodation suggestions in these places - Maentwrog, Ganllwyd, Commins Coch, Dylife, Devil's Bridge (Pontarfynach), Pontrhydfendigaid, Rhandirmwyn (Rhandirmwyn Bridge), Llandovery (Llanymddyfri), and Glyntawe. Any helpful suggestions are greatly appreciated.

There's a hotel right on the side of the A470 in Ganllwyd "Tyn-y-Groes hotel".  I have not stayed there but have used there restaurant on many occasions with no complaints.  Popular with MTB as they have secure bike storage.
