Mathilde (from France): All depends on where your office is located. In the south the expat districts (for residential and life quality) are Breach Candy, Malabar Hill, Kemps Corner. And in the north Worli, Lower Parel, Bandra West, Khar West. However, there are also the most expensive ones. If you cannot afford such rent, Andheri and Powai are two areas which are expending and have good quality flats for the price.
Rakhee (from Australia): Bandra is certainly a good place for an expat with a diverse population, both local and expats. Mumbai is a big city and there are many new pockets that I am still exploring.
Lindsey (from England): Most expats live in Bandra, Juhu or Powai. We used to live in Bandra but decided to move to a new building in Andheri West where you get a lot more for your money. The nicest place to live is South Mumbai as there is a very different feel to the old city. The architecture is fabulous and the streets are clean and wide. However, most international schools are in the northern suburbs.
