Le Mridien Nirwana Bali
Beautiful setting but mediocre rooms. View of ocean from rooms mainly obstructed by coconut trees. Breakfast at the outdoor seating overlooking the golf course and Tanah Lot sea-temple is magical !
Plenty of daily activities within the resort, I could stay there for a week without leaving. They also have a free shuttle service to Kuta or Ubud, depending on the day of the week.
Platinum upgrade to Executive Suite, but no comp breakfast or drinks voucher. I believe one can upgrade to a 1 BR luxury villa using instant award at 6,000 starpoints (from exec suite) or 7,500 starpoints (from deluxe room).
May not be the best place to stay for those on their first trip to Bali due to its isolated location; but if you are content staying at the resort purely for rest and relaxation, I dont think theres any Cat 1 (or 2, 3 or even 4) property in the world that could match the setting here.
