I would suggest Candolim, its nearer enough to the noisy Calangut [ the outdoor nightclub there goes on until about 4am and can keep you awake if staying near by] but quieter and you will be able to get to the fleamarket etc.I have stayed a the Victor Exotica in Candolimand can recommend it.
Where I like to stay is Bon Appetite[ look it up on the net] owner ia guy called Joe, next to Taj hotel at the very end of Candolim they are on the beach with a good restaurant and behind the restaurant are bungalows with tv, a/c, nice gardens with hammocks to relax in but might be a bit too quiet etc but their sun loungers face the beach.
Whatever you do though dont go "all inclusive" there are loads of nice restaurants & bars to try and not expensive [ starter.dinner & dessert & drinks and you will get change from £20] bottle of Vodka in a supermarket under £5, so why tie yourself done to eating in same place for 2 weeks ?
dont take any tours they are a rip off instead ask your friendly taxi driver how much to take you to wherever you want to go and bring you back [ they dont charge waiting time] haggle a bit first.Dont forget to visit Spice Fields well worth a trip.
There is a lovely beach restaurant in South Goa owned by a guy called Sergio I think its called Zeeboka its in UTORDA [ pronounced OOTORRDA] well worth a visit, ask your taxi driver he will know, because its a bit way out they feed the taxi drivers for free [ they have their own little waiting area] so the taxi waits for you no matter how long you stay, the lobster, crab & shrimp is out of this world , three musicians come and play for you etc its a well kept secret but worth the ride.Another good restaurant is Souza Lobo in Calangut.
If you stay in South Goa it will be relaxing but very quiet.
other people will probably have their own favourites to recommend, its worth paying extra for A/C [ air conditioning] dont forget your roll o
