In my experience, it's usually nice & quiet - a lovely old fashioned city centre square. Slightly wild & overgrown - feels like a Lewis Carrol novel in places.
Nice secluded playground too for younger kids. Near the National Gallery which is also worth a visit (for both art and lunch!).
Merrion Square. Near Pearce St Dart. Lots of bus services. 2 minute walk from Stephen's Green, or Trinity College (East side).
