Trish's place is conveniently close to Killarny's city center, probably less than 10min by foot. What we saw of the house was very nice, the room was basic but very clean and cozy after all. The bed was so comfy that my girlfriend didn't want to get up. :)
Bathroom just as clean.
Trish herself helped us with a question we had in advance and her daughter gave us some directions. Didn't see Trish herself but she seemed super nice from the texting.
Would definitely recommend the stay if you'd like to look around Killarney for a day or two!
