These are simple cabins in a beautiful rainforest setting. Keep in mind that there is no air conditioner or hot water (just a fan and screened windows), and the road in is steep dirt/gravel. Be sure to watch for signs as you are coming in or you will miss the road.
The beds were not very comfortable, but the rooms were clean, and the cabins are private. The breakfast was typical Costa Rican food. We didn't get a chance to go to the waterfall on the property because there was a big rain storm when we got there, but we were happy to listen to the rain and thunder instead.
We did have a problem with our room. In the heavy rain, the toilet overflowed with clear water all over the floor of the bathroom and into the room. They didn't have any other cabins available, so we ended up just sharing a room with the couple that we were traveling with and just paying for one cabin. This worked out fine for us.
If you get a chance to go to the nearby Nuayaca Waterfall while you are there, I highly recommend that. It was our favorite thing we did in Costa Rica.
