The Delgany address is a little bit cheeky. As stated earlier Kilcoole and Charlesland are closer. The road to Delgany village is narrow and dark (Priory Road I think its called). Its not the sort of road you would be comfortable about walking at night.
The estate is quite close to the new road. Remember once it opens it will be a fairly busy one.
On the plus side there is plenty - close to sea, mountains, golf course, plenty of cycle lanes, new shops, swimming pool opening soon, DART to town is 55 mins.
