theres a kindi at myers park top end of queen st, have a bit of a waiting list but when we looked into it it was around $200 per week for 1st child. last i read the bottom was falling out of the apartment market so theres lots about. but dont quote me on that, have a look at the old propperty sections on nz herald site that's had a lot about the apartment market in cbd recently with quite a few places failing to sell at auction so i would presume theres some bargains to be had out there. Although these may be some of the chicken coop apartments with not much space.
word of warning we lived in an apartment on queen st when we first got here, it was quite noisy even up on 15th floor, and wasnt ideal for us because of the kids (3 and 6) but theres a few nice parks about near CBD to take them so its not all bad.
