If you're looking for the authentic experience, then this is it! The air conditioner probably doesn't work, but apart from that, the room is pretty great. Given the modest price, don't expect the bathrooms to be too neat, but, given that we were there for 2 days in the rainy season, we used to sleep in the hammocks or the beds by the waterfront anyway, so we didn't spend too much time in the rooms. The experience of sleeping out on the verandahs was simply one of the best experiences of my life.
Our host, the woman who owns the guesthouse, has some really cute kids and dished out the most amazing food. The menu has hundreds of items and they're all available and all really good! If you take a look at the fruits stand that's in the restaurant, there are some interesting fruits in there, we had a durian for the first time in our lives (it was pretty great!)
One of the most peaceful experiences ever, superb value for money, if you're finicky about neatness etc, probably not the place for you, but if you like to rough it like we did, and if it's rainy, so not too hot, then this is the best place on Don Khone, no kidding!
