Does anyone know this house in Mumbai?

My grandfather and great-grandparents lived in Mumbai from around the year 1900. I have some photos of the home they lived in and would love to visit it (or the site where it existed) whilst I’m here. One of the photos refers to it as “Moonim Villa” on the back but I can’t find anything when I search on that name. If anyone knows the location, I would be very grateful. Thank you
