Well there's the Taj in Sinquerium/Candolim, but if you're coming to Goa you don't need 5*, ok a nice pool would be nice, but how much time are you likely to spend in your room? There's also the one in Panjim... Big chain but can't remember the name of it... (but that's a bit out of the way as it's in Panjim...
If you're wanting that relaxing pampered holiday then go south... Otherwise get a cheapy off teletext ...
Thanks
