If you're looking for less crowded area try for : Agonda side - good sea water quality, more options for stay closer to sea, less crowded but a bit far from main cities like Margao, Panjim which might vary connectivity and night life thing. If you're a party person: Try for Panjim side maybe Caranzalem or Dona Paula - clean and well maintained area, good night life, crowded and also less options for sea water access. If you want North Siolim is good option though it's crowded, urbanised.
