The deceased, identified as Manisha Bhave, was a divorcee and was staying alone for the past 12 years, an official said.
Bhave used to teach at a suburban college.
The incident came to light after Bhave's neighbours called up the police complaining about a foul smell emanating from her flat, he said.
A police team that reached the spot found the door of the flat locked form inside, following which they broke open the door, the official said, adding that the woman was found lying dead inside the house.
The body has been sent for postmortem.
Police have registered a case of accidental death and are awaiting the postmortem report, Thorat added.
