Have a look at the plaza apts in Ballymun. I believe the metro line is due to run near by (if not literally outside it), new IKEA will be huge for the area and above all it's next door to DCU which means u are never going to be stuck for a tenent.
People laugh at the notion of living in ballymun but they also laughed at the notion of the docklands area 10 years ago..look at it now!
As for the price, at that money...consider all your options. Me, I'm moving to the country.
