Gated complexes and pre-schools in Koramangala (Bangalore)

Hi- I am new to this forum. Will be moving to Bangalore for 7 months in November to conduct research for my PhD. My offices are based in Koramangala. Can anyone recommend any gated complexes with pool, kids play area etc in Koramangala- have a 2 year old so keen to have somewhere for her to play. What sort of price would a 3/4 bedroom apartment command?

Also, can anyone recommend any pre-schools which have a mix of international kids?

Thanks!
