We booked for 4 nights and got upgraded to Premium room for being a member of Marriott Bon Voy, I think. Premium room was spacious with semi walking closet and spacious balcony (new building), great for our family of four with 2 young children. Balcony for other type of rooms in the main building seems not too big so this was great. The premium wing also has their own pool, but was closed during time and guest should use the main pool. All room facilities are top notch, service was fast and warm especially with the young ones. Toiletries are from their Heavenly Spa, and the shampoo is really soft to the hair, love it! Electric plugs are a lot, around 4 in the room and appropriately located for charging all gadgets but still room for making hot water and hair drying while at it. AC is very cold and any kind of adjustments take no affect. The staff recommend to turn it off and it works for us because it's still cool without the AC on I don't know why. Really love what the hotel offers for children starting from day 1: drink bottle, free ice cream daily for kids, canoe, and abundance free kid activities to keep them happy. We've stayed in other hotels in Nusa Dua and pretty safe to say Westin is by far the best when it comes to children activities and facilities and the staff attentiveness. The garden pathway from room to beach was also the highlight because it was beautifully maintained, and the view of greeneries meet the blue ocean will stay on our mind for a long time.
