Hi there, this might be a little late ... I've lived in North Strand for nearly 10 years and here's how I see the pros and cons:
Pros:
Good sense of community, there's a mix of long term residents who in general are thoroughly decent people and professionals who have bought in the last 15 years or so.
Lots of good shops and places to eat - including a great Italian restaurant and possibly the best Japanese food in Dublin, Cusacks is also a very nice pub, with nice people.
Lots of amenities close by - Dollymount beach, parks etc.
Obviously it's very close to town, croker, the point etc.
You never have to wait more than 2 mins for a bus/taxi!
Good options for schools
Cons
Yes, there are a few knacks/cheeky kids around, most of them are harmless, that said, I've never had any issues.
