Martin and Sinnaid's appartment is easily accessible from the airport, city bus and 30-40 minutes to be there. Then, you are in the north of Dublin, about 20-30 minutes by foot from the city center and the famous Temple bar street. The neighborhood is fine, nothing to declare !
The room is nice, bed confortable and the share bathroom really clean. I did not have to use it but you can use the kitchen if you want. To be brief, when you see the prices of the hotels and other airbnb in Dublin, do not hesistate to pick this one !
