In many ways this is a step down from camping in a tent, since in a tent the bugs stay outside of your living space.
First, understand what you’re renting: an open-air shelter that has a roof, a wood floor, two beds (one queen & one twin), & a bathroom. The beds are covered by mosquito nets that have enough rips in them to allow insects through. The attached bathroom is the only room that has a door that locks, so anything that you want to keep secure must be kept in the dirtiest room. The bathroom is made of stacked stones held together by mortar, & it looks like whoever built it had never made anything like this before & was both drunk & trying to finish quickly. When I arrived the bathroom contained an abundance of insects, both living and dead (the star: a dead cockroach that was around 7cm / 3 inches long), & both the living & dead bugs multiplied over the course of my stay (the star was joined by a 9 cm / 3.5 in roach). On the plus side, you can see & hear the ocean from both beds. The entire property was clearly built by very short people. If you are of even average height then you will bang your head against overhead obstacles multiple times during your stay, both in the room and in the public spaces.
Second, there is nothing nearby. Unless you have a car then you have no options other than enjoying the wading pool, the rather small sandy area they call a beach, or using their free kayaks. The on-site restaurant is mediocre and overpriced, even for Samoa.
