LivLand, we're living on Mourne Road in Drimnagh and I really like it. It's not the best place to live in the world, but certainly not the worst and it's really handy for town. The bus is regular, the LUAS is only 5-10 mins walk away tops, the mortgage is manageable.
There's a couple of houses on the road for sale through Mason that have been on the market for ages - you'd probably get a decent deal at this stage. On the other hand, I saw a Sold sign go up on a house on Belbulbin Road which wasn't on for too long if memory serves me right.
