Yes, indeed, the new St Regis supposedly has outstanding villas, brand new. Hope to visit them.
Alternatively, if you want a better location with access to more restaurants and more things to see and do, look at the two bedroom villas at the Samaya, in Seminyak. Very well done and likely less cost than the FSeasons. They are now being updated and, by the summer, should be brand new. Great small spa at the Samaya, terrific service and smack on Seminyak beach where you can watch the world go by. We found Seminyak much preferable to Jimbaran. Have fun, Bali is terrific.
