Tom and Noreen were really nice hosts. Still running on continental time we were way too early, but they fixed the room really quick for us. The room itself was as described, a bit small but really you're in Dublin and need it for sleeping only ;)
For us the location was perfect. Everything for daily life is reachable by foot e.g. grocery and the next bus stop to the city center just 200 m away and then about 20 minutes. Use the Leap or Do Dublin card for easy access. Otherwise have the exact amount ready in coins!
Last but not least the cafe Tom and Noreen are running, Fothergills, serves really good food.
