Where to live...?

At the moment we are looking into moving to the Busan- area. My husband has been offered a job in Okpo, whereas the closest IB-school I could find in the area would be BIFS. My daughter is just turing 10, so I would not like her to sit on the school-bus too long, and the same issue arises for my husband. 

At the moment we are spoilt with all condo-facilities here in Singapore, walk to the grocery-store, and "subway" and buses stop next to the condo, important as I have no car here. We appreciate living away from the typical expat enclave, to be able to see a more local lifestyle of the people, but enjoy the international environment and the bunch of kids we have here in our condo. Easy daily life routines is more important rather than a fancy, flashy new apartment......

Any suggestion for a nice and convenient area to live?
