I used to live in an estate called Glenbourne, it is supposed to be leopardstown, but it is really an extension of Ballyogan.
I would not recommend living in this estate, it is very badly kept and managed, grass and trees are all a disgrase, one small common grass area for children to play and only a fence away from ballyogan. Young 'hoodies' hanging around the shops, outside the Gallops (the pub) frequently walking around Glenbourne and drinking in the area at night.
We only lasted 6 months in Glenbourne and had to move out. I am sure there are some lovely parts of Leopardstown, but steer clear of this estate.
HTH.
