Where are you working? With Adamstown next door, the traffic in that area has gone mad. Your problems are potentially many
1 - getting out of your estate
2 - if you have to turn right to head towards Superquinn
3 - getting from there to the N4
4 - getting from the N4 to the M50/into town
Then again with the Adamstown train station you might be okay if you only need to get to town.
Finnstown is okay, depending on how close you are to the LL you may have trouble with noise from the smokers/kids playing outside. On the plus side you have a Spar, a pub, a great Chinese, a medical centre and a pharmacy on your doorstep.
