If you want an affordable option smack dab on the beach, stop looking right now and book here! My cousin and I were looking for a room with 2 beds for our trip to Providenciales for another cousin's wedding. Sibonne was by far the cheapest option on the beach for the 2 of us (although if you're traveling alone, I don't know that it's all that much cheaper than other hotels). Based on other reviews, I was not expecting to love the place. However, Sibonne exceeded all of my expectations. Our air conditioner worked EXCEPTIONALLY well and was not loud at all (if you're a light sleeper, bring ear plugs; it's common sense); my bed was super comfortable and I slept great. I also loved that the place had a really relaxed feel and had mainly an adult crowd (not many screaming, crying kids). The beach chairs were all very comfortable and in great condition (I think they must be new) and there were always some available. There are even two hammocks by the pool if you're looking for a different way to relax. My sister stayed 2 mins up the beach at the Sands, and their beach was always packed with children and all of the chairs were taken. (Besides, if you really want to swim at the Sands' pool, you can just walk right up and swim there! There's no regulation.) The restaurant was a perfect, convenient option. I highly recommend the breakfast tart + Bloody Mary from the Sat/Sun brunch menu! Plus, you won't find an oceanfront hotel restaurant with a better view. The beach towels (disparaged by other reviewers) are perfectly fine and serve their purpose. If you want a big, fluffy beach towel, just bring one! If I return to Turks and Caicos and am looking to split a room with a friend or family member, I will stay here again without question.
The "ocean view" from the second floor rooms was not quite what I was expecting. Your window looks out onto the courtyard (which is very pretty) and you have to actually go out on the balcony and turn to see the ocean, plus the visibility is somewhat blocked by palm trees. That said, within 30 seconds of leaving your room, you're actually on the beach, so it's not that big of a deal. In sum, it is nice to have the balcony, but I'm not sure it's worth the extra cost.
I recommend purchasing snorkel equipment back home for $10 at Walmart or Target, because Sibonne does not provide this, unlike some other hotels.
