Hi
I would defo consider The Park in Cabinteely too. It has an 110 acre park, with excellant playground and other facilities. It has St Brigids National girls school which is also excellant, lots of kids activities locally, the luas is coming in nearby, 24 hr shopping at Cornelscourt Dunnes Stores within walking distance, on the n11 bus corridor, straight run into UCD and town by car. V v safe area- see other thread. Leopardstown race course and gym etc..Only downside is the pubs are not v exciting but still do-able.
Sandyford less then 10 mins by car. The Park is about 1 min off exit 15 on the M50
5 mins drive to Killiney beach, 10-15 to bray Beach, 15-20 mins to Greystones beach.
Shopping also at Carrickmines- 5 mins by car.
Nice free library in Cabinteely village, has good childrens section.
