Anaheim is a good place to raise children and some areas are better than others. I have been living in Anaheim one mile away from Disneyland for about 27 years. It is central to a lot. Different cities, freeways, shopping. Of course, there are different school districts within the city.

I could also help you in finding a place to rent or buy.
Katella is one of the streets that separate Anaheim and Garden Grove. Down around Euclid, if you were on the North side of Katella you could be in Anaheim, if you were on the South side of Katella you could be in Garden Grove. Hope this helps...
