I've lived on goldenbridge avenue for the last 12 years. It's very settled as other posters have said. A mix of retired people, families and a few rentals, but I've never had any problems with noise or anti-social carry on.
I got broken into once by a 50 year old junkie, but he was a serial breaker inner around south dublin so I was just unlucky he pickedy house on that day.
The big plus for me is how quiet the area is yet you can walk into town in a half hour.
The last of the st michaels tower blocks was knocked a few weeks ago. It was a bit of an eyesore so can only improve the area.
