I stayed in The Westin Resort, located at Nusa Dua. Nusa Dua is more quiet, all the 5 stars hotel are located mostly there. Westin is more of comtemporary style. If u like Balinese style, then hv to try other hotel.
If just go there relax, do spa, and hv romantic dinner, its quite a good place for honeymoon. But if u intend to shop alot, advise u all stay Kuta area where there are alot of tourist. Beach there quite nice but will hv some harrassment from the locals as they will surround u to ask u to buy their things. Ubud area hv nice restuarants and cheaper things.
