Best Localities to stay and schools near Edenvale (Johannesburg)

Hi Everyone,
I am Indian currently living in Tunisia and planning to move to Joburg in Dec-Jan. My office is in Edenvale and wanted to know best localities nearby where i can stay with my family. Is there any specific locality where more Indian families stay. Also what are the best schools options for expats and whether difficult to get a seat for my Kid or generally its easy to get one. Please help!

Thanks
