Looks a bit like a hotel I stayed at in Tahiti called Kia Ora on the Rangiroa Atoll. Don't have any of my own pictures with me but here is one from their website. Of course it could be any one of dozens of hotels in Tahiti or the South Pacific as many have over the water bungalows like that.
And we didn't have a hot tub.
Nice but a bit spendy. Only stayed a couple of nights as a splurge. Otherwise we tended to stay in more economical accomodations.
