The staff is the best, always friendly, trying to help and proposing all the surrounding activities at a very low price. They found us an amazing guide to the national park, to trek in the jungle and to do some bird watching. However, I recommend divers to dive and not to snorkel, it's expensive but totally worth it, compare to snorkeling which is just expensive from my point of view.
The room on the other end, (we had a regular one) was very small, not very clean and the bathroom is the minimum you can expect: a shower with only cold water and directly next to the toilets without any separation.
All in all the home stay is awesome thanks to the people but I would recommend you to take a luxurious room at least for a bit of comport. And try their mango, it's the best I've had in the island :)
