Great place, great host. Very clean and comfortable, and Mary gave us some great insight about getting around Sligo and the surrounding area. A breakfast of cereal, toast, coffee, and juice was provided each day (and she graciously and very kindly accommodated our dietary restrictions).
I would say the only downside for some would be that, as the listing states, the kitchen is not available for use. We had no problem with this, but it could have been difficult if we had been staying for longer than three nights.
All in all, Mary works very hard to make this an outstanding Airbnb experience. I highly recommend her place.
