Nine of us headed up to donegal for a weekends racing for at halfway karting for a 30th birthday and we stayed in Eric's B&B. There was plenty of space, two living rooms we didn't use one of them at all but for family stays I can see how this would be great. the place was spotless and we had a great stay.
It is well located within a 30 min drive from halfway karting, 5 mins from Carndonagh and in the other direction Ballyliffin where you can find the world renowned sea food chowder in Nancy's Barn restaurant. loads of beaches with a 10 mins drive and the beautiful Glenevin Waterfall.
So all in all a great part of the world to visit and Eric's Air B&B is a great place to stay if you are visiting the area.
