Hey,
Yep its a really nice area i think, i live not too far from there. I did believe the murder was at Shankill train station....however i just googled it and it was actually a stabbing which left a 19 year old in critical condition, a bit different but scary none the less.
Its like everywhere i suppose, once you arent going to let your kids run riot around the place and be out at all hours you can keep them safe.
nice pub in the village, late night opening chemist, barber shop, credit union, video shop, nice chipper, near a dart station. Good schools in the area - Johnstown in Killiney is a great school
good luck!
