Tony's place is in a great location for exploring the city of Kilkenny. We came in on the train from Dublin, and we were able to walk to the apartment in about 10 minutes. Check in was incredibly easy and quick, and there is someone at the bottom of the stairs that can help you if you have any problems at all. We ate some great restaurants that were less than a 5-minute walk away.
One night, it was little noisy on the street. So keep that in mind if you are a light sleeper. Its a great place though, I'm a light sleeper and I'd still stay there again in a heartbeat.
