We stayed in the apartment for 3 nights. It is located on Killarney's main street, close to shops, restaurants and pubs. The area is lively, saturdaynights can be a bit noisy but I slept like a baby with some earplugs.
The apartment itself was even better that imagined. Very comfortable, everything you might need is there. Fast WiFi, well equipped kitchen and the washer/dryer combo was very handy. John is a nice host, check-in was quick and efficient. Would totally recommend this apartment!
