Donal was one of the nicest, friendliest, and most accommodating hosts I've ever come across. Communication with him was really easy from the get go, and when we arrived in town, he volunteered to come pick us up from right from the bus stop and drive us to the house (the drive included a quick tour of the town with lots of history thrown it).
The house we stayed in was about a 20 min walk outside of town, but with Donal always willing to chauffeur us, we never ended up needing to hoof it. The house was extremely cute and and livable, and unchanged from when Donal's parents used to live in it, giving it a vintage Irish house feel. What's more, the house was extremely clean and stocked with food for us to munch on in the morning.
We had absolutely no complaints about our stay at Donal's, and it put the cherry on top of an extremely fun weekend in Killarney :).
