Sofitel Bali Nusa Dua
The bathroom amenities are in black and simple Sofitel branded.
There is a bar by the beach that serves a seafood buffet for dinner at IDR300,000pp.but during my time there I hardly saw anyone there. Also it's BY the beach and not in the sand.
Instead I rather suggest booking a UBER to take you to Jimbaran bay where all the "in-sand" seafood places are with a nice atmosphere.
Uber works great in Bali, it's super cheap and not a ripoff like the taxis there. Jimbaran bay is 10mins from the hotel.
