I don't think I can give Susan and the Siding B&B enough praise. It's a beautiful house, just outside of town, with a great view of the countryside(Lahinch is amazing in it's own right...), yet very accessible and easy to find. The accommodations at the Siding are very nice, and the common room has a beautiful fireplace that Susan made sure to keep stocked with coal.
The proprietress and her husband were both exceedingly accommodating, as they picked my Girfriend and me up at the bus stop in town, and dropped us off again at the end of our stay. I even got a lift into town for my morning tee time at Lahinch Golf Club (also AMAZING!!!). It's worth noting that the B&B is within walking distance of town, probably a 20 minute walk, and there is a side walk the entire way. It's a beautiful walk if it's not raining.
Susan is also a great cook... I recommend the full Irish breakfast (the white pudding is great, but I opted out of the black), and DEFINITELY try any muffins or baked goods that she offers!
All in all, The Siding B&B is a lovely place to stay, with a friendly and accommodating proprietress(and family), great breakfast, and very nice rooms. I don't think you'll find a better value in Lahinch!
