I booked Mary and Sean´s room on the behalf of my parents for a couple of days, because they visited me in Dublin. We, especially my parents, loved it. Mary and Sean are very friendly, helpful and accommodating hosts. For visiting Dublin and its surroundings, I think the place is perfect, because of the nearness to the DART (less than 20 min to the city center. Day trips to any area outside Dublin, therefore, are easy as well. ( DART as well or rent a car)
We can highly recommend Mary and Sean´s place!
