We weren't completely sure what to expect when we stayed here, and we left feeling somewhat conflicted.
First off, the property is absolutely beautiful! We could just sit in the chairs out front and listen to the ocean and jungle for hours! And the location is perfect for exploring the road to Hana.
However, I would note two things:
First, the Indian Room is not the quietest room. We had the windows open pretty much the entire time (to get the cool breeze), and the room is directly above the shared kitchen in the main house, so anytime anyone was cooking, it got to be pretty loud (specifically morning and evening). Also, the front and back doors were very noisy every time someone used them, which was frequently. There were also workers/volunteers staying in a building behind the main house that were loud late at night, as well. This all made relaxing in our room difficult after a long day out.
Secondly, the eco retreat is definitely off the beaten path on Maui, while beautiful, you'll be driving a lot if you're looking for easy access to beaches and restaurants. That said, if you're more interested in hiking, then this is the perfect place to stay.
