My partner and I stayed for one night in Killarney on our way back to Dublin after a wedding near Galway. It was less than a 10 minute taxi ride from where the bus dropped us off in town to Juliann's house. When we arrived, she greeted us warmly outside and showed us to a clean and inviting bedroom w/ a private bathroom. We found the bed to be quite comfortable and we slept very well, especially after exploring the area for a few hours on foot. (Just mind walking the narrow roads when it gets dark)
sidenote: There are plenty of great places nearby to grab a bite or a pint; we opted for GoingGreen for lunch and Killarney Brewing Company for dinner. Both really good experiences.
In the morning, Juliann made us a delightful breakfast of yogurt, granola, & banana with OJ, coffee, & homemade scones! She dropped us off a few minutes down the road at Killarney National Park after we ate , and even helped get our bags to us right before we needed to hop on the train. Juliann was a most gracious and accommodating host who made our stay in Killarney extremely pleasant. Our only regret is that we didn't stay longer!
