To get back to topic, Goatstown is a nice area to live in; I lived there for a few years about a decade ago and although I know it’s changed I’m not far from there now and can see it hasn’t disimproved.
It’s got a similar look and feel to Clonskeagh but is just that little bit further out of town. As indicated by other posters, crime and anti-social-behaviour levels are low; you can safely walk around at any time of day or night and vandalism/graffiti are rare. Would be a good place to bring up kids.
The Irish Glass Bottle sports club site you referred to is nothing like the IGB site in Ringsend and I don’t think it should cause you any concerns.
