I stayed in Dublin for work for four weeks, and this flat was an ideal base for me: very close to a bus route and a Tescos, 1/3 of a mile from Phoenix Park, the right side of Dublin for the airport, and about 20 minutes walk from central Dublin.
The flat was very clean and quiet, and Liam was an excellent and helpful host. Bed was large and considerable. Linen and towels are provided and are replaced every week.
Wifi is reliable, but make sure you connect to the right router! (Liam can advise.)
Overall, a happy experience.
