It was clean, private, and comfortable. There was extra sunscreen and mosquito repellant in the bathroom. There was also a broom underneath the bathroom sink, which is especially useful since you're getting sandy everyday. Marianna also provided snorkel gear, which was a nice touch.
Aside from that, the rest of the Airbnb felt kind of carelessly put together: one of the fans was broken, there were holes in the sheets (I woke up with my leg poking through the edge of a sheet one night), the beach chair provided was broken, the toaster was difficult to use (wouldn't stay in down position), the can opener didn't work, and some bowls looked dirty and the plates were too big to fit easily in the microwave (had to angle them to fit them inside).
So none of it was a big deal. Definitely liveable. Just felt very carelessly put together.
