We were a group of 4 who decided on a last-minute trip to Kilkenny. Tony got in touch a few days before we were due to come down to let us know how to get to the apartment, and again the day of our arrival to check our times so he could put the heating on for us!
The building was incredibly central - less than a 5 minute walk from where our bus left us in the city centre, and less than a 5 minute walk from Kilkenny Castle. When we arrived we were brought straight up to where we were staying.
The apartment was very clean, had lovely furnishings, and very cosy feel. Though the street gets very noisy at night (which we had known of beforehand), we all slept very well.
I'd definitely come back, and I'd definitely recommend it to friends. The only people I would not recommend it to are those with mobility issues, as the building has no lift and the apartment itself is two-story.
