Indeed, if you're allergic to noise and don't like wearing ear plugs, this is not a place for you. You really 'enjoy' the sound of Killarney, mainly during the weekend nights.
However, if you don't mind, the appartment is conveniently located in the town center. At walking distance of pubs, restaurants, supermarkets (2 minutes), train & bus stations (10 minutes). You can also easily access the National Park on foot.
The appartment is conform to the description and pictures. It was comfortable for my 1 week stay, well equipped and with lots of extras (soap for the washing machine, ear plugs, tissues, etc.).
I didn't have the opportunity to meet John and Melanie but communication was very good and I could have contacted them should I have encountered any problem during my stay (which was absolutely not the case).
