The B&Bs we stayed at in Ireland last June were amongst the best that I have experienced anywhere. The hosts invariably made us feel like we were visiting family, yet respected our privacy. We were routinely welcomed on arrival with at least tea being offered by our hostess, often with baked goodies (cookies, cupcakes, and warm pear crumble – yum!). Breakfasts were plentiful and always good. We were sent out with a sing-along one morning, and other mornings with fresh scones, a packed lunch, etc.. All were spotlessly clean, had easy parking and free wi-fi. On a couple of occasions, we were offered a ride to a local pub, so that we could enjoy more than a pint ;-)
We were very happy with all of our B&B choices and would highly recommend each and everyone of them:
Just south of Armagh: Dundrum House Farm B&B (sheep)
Between Coleraine and Ballymoney (near Bushmills): Brown's Country House B&B
South part of Belfast: RavenHill Guesthouse
In the Ranelagh area of Dublin: Colette Carter B&B (3 min. walk to Luas Beechwood stop)
On the Dublin Road, coming into Kilkenny: Dunromin B&B
In the countryside, just a few kms outside Blarney: Claragh B&B
Just up from the main street in Kenmare: Abbey Court B&B
In Annascaul, on the Dingle Peninsula: Old Anchor Inn (understandably, a favorite with hikers and cyclists)
In Fanore, in the Burren region: Orchid House B&B (seafront, with a beautiful garden and cows)
Near Newmarket on Fergus and Shannon Airport: Cahergal Farm House B&B (horses)
Please feel free to add your favorites to this list! :-)
