My stay in Dublin for 3 nights with my 14 year old boy was great in Micheal's flat.
Everything was as described, clean, spacious, so convenient with public transportation or on foot to the city center, a few minutes away from a bus 747 stop to go direct to the airport... Confortable and so practical with these details that made us feel at home... like the hook in the bathroom to hang out clothes or the bin (vital for a woman with long hair) or sugar and salt at hand in the kitchen and so on.
So close from the city center and so quiet! Just fine to sleep well anytime. And we always felt safe going back to the flat on foot at any hour in the evening.
Moreover Micheal is a perfect host, accomodating with arrival time. Furthermore he is so fascinating when he welcomes you and tells you about Dublin and the history of Ireland. He knows so much that he should maybe think about offering a new service like spending 2 hours with him for a quick tour of Dublin on arrival!
