Hi there,
I live in Rockview apartments - you can walk down to Dundrum from Rockview through Sandyford View, Bracken Hill and then Kilcross. I walk to work most days and go through Kilcross. It seems fine - was talking to someone recently who said years ago it was a no-go area but is much more settled now, and houses will probably be very much in demand there in the next few years. There is a building which is currently all boarded up and I heard it's being turned into a medical centre...
