Mary and her family were all a complete joy! From a welcoming hug (after a long flight and harrowing drive), to having the place ready and comfortable, our group of 4 had a great time being able to use her room as a home base to explore Dublin or go to NewGrange for the day. The breakfast was great but her kind and helpful nature was even better - from directing us to lunch or dinner, or how to park, she helped make the trip.
Our only word of caution is that there are other guests at her place, and it is close to city center, so it can be noisy. But we all slept extremely comfortably!! Just perhaps not a place for people who was solitude and quiet.
