Best Areas to Live in Mumbai

Hi all,

Can anyone please respond on InterNations (not directly to me) and tell me what the better areas are to live in Mumbai for an expat married couple speaking English?
My office is in Navi Mumbai so closer to this, the better. No kids, so schools not important. Quality of accommodation would be my prime concern, with amenities like restaurants and entertainment, secondary.

Looking forward to read more!

Thanks in advance,

Mitch
