Hi,
5 years ago I moved from Sligo to Dublin, We bought on Castleview Road in Clondalkin and have lived there since. We are very happy here. I also work in Clondalkin, in the Wyeth Biotech Campus, so I only have a short commute to work.
The Village has everything that you would need, Mill Shopping Centre with Dunnes, plus other small shops, with loads of free parking. Theres also Tescos. Few nice pubs, well run with a good village atmosphere. Some top notch restaurants also. The village also has one of the best preserved Round Towers in Europe, a thriving Gaeltacht culture, excellent schools, football clubs, a community centre which is currently under renovation with new swimming pool, gym, outdoor games fields.
Corcagh Park is a beautiful area which has undergone massive re-design and landscaping over the last few of years, with managed fishing lakes and wetlands with a good variety of birds.
Public transport is good with a fair numbber of busses, and of course the luas.
Grange Castle Business park is only 10 mins drive away, and I expect there will be growing numbers of employment opportunities as the years go by.
Of course, as with ANY area some areas are more popular than others. As previous posters have said, anywhere within 10 to 15 mins walk from the Village itself are probably the nicest and most convienient, however there are some nice established areas outside it aswell. I would recommend you come and have a look anyway!
