Clontarf is a wonderful and quiet area next to the Dublin port. Daire's home is amazingly beautiful and cozy. There are lots of coffee shops nearby and a great supermarket also. In terms of transportation, you have a bus stop right in front of the house and the Dart is just 7-10 min walking distance, making it really easy to get to the city center or any part of Dublin.
Daire was really welcoming, I arrived a bit late but he waited for me and provided me with all the necessary info about transportation from the airport. The room was exquisite, really cosy and warm, with a personal bathroom. The bed was amazingly soft with fresh linens (I actually couldn't get up in the morning :)) ). The room is packed with goodies (coffee and a coffee machine, tea, biscuits, pretty much anything you need).
I had to work each day (going out in the morning and arriving late) so I needed a good rest each night. The house is really quiet, I slept like a baby in the softest bed possible.
Daire is amazing and his home is beautiful. I recommend it to anyone who travels to Dublin for vacation/work.
