Need advice on a coastal trip

Hi All, My mother is here from Punjab and I have three days on the weekend to take her to a beach. My options are GOA or Ganapatiphule. Could you help me choose? Considering the time that I have, I am more inclined towards Ganapatiphule. I heard the beaches are clean and it is not so commercialized. If there is anybody who has been there recenlty and would be kind to share the experience?
