Canices would be good if you are on that side of the town.Quite a musical school.
If on the other side perhaps St John of Gods,boys in one and girls in the other.
Talbots inch would be my first choice to live in,the houses are stunning,all different and some over a hundred years old again that would be the right area for Canices.
If on the other side,you could try Maidenhill,which is a very nice estate,all individual houses and all very nice and just up the lane from the John of God schools.
Rental properties are ten a penny ,and most of the estates are within walking distance to the city /schools.
You could always rent out in the country side? Much cheaper,much bigger house,no traffic,much more land etc..just to see if you like it..I would stay away from most of the very new vast estates which tend to be around the Newpark area.
You should love it there,its a fabulous city,very welcoming and very convenient..Lots of shops/pubs/clubs/entertainment..cinema/bowling alley/take aways/restaurants.best of luck with your move.
