Assisted living for elder parents in Mumbai, Navi Mumbai or Thane

Hi all, looking for a nice, well cared for assisted living place for an elderly female relative. She is in Mumbai but it is getting hard taking care of her in an independent living setting. Limited mobility and medical ailments severely limit her abilities to care for herself. Need a nice assisted living home where she will be well cared for. Her children live overseas and will visit her every 2-3 months - so central location like Mumbai is important. Also she has family in Mumbai so don’t intent to move her out of the city. Higher end assisted living homes is what we are looking for. Any suggestions?
