I absolutely loved staying in Louisa's hut. Just be aware that you won't have much reception, if any. That's just the nature of being so close to the coast and far from downtown Pāhoa. I didn't have reception for ~30 minutes prior to arriving to Louisa's place. As long as you've got your maps setup you should be fine. Louisa also has wifi so that helps with planning what and where to check out in the area. She's also a great guide knowing when the local farmers market is happening and other attractions.
Either way, loved staying here as it allowed me to disconnect. The symphony of nature at night was personally soothing to fall asleep too. The weather was perfect. Looking up at the starry night was otherworldly and inspiring. Kehana Black Sand Beach is great. I love how carefree and chill it is. It is a clothing optional beach, not much space to spread out on, but nonetheless a very much laidback environment of both locals and tourists.
I would definitely recommend anyone to experience Louisa's hut and Pāhoa. I'm heavily reconsidering doing so again next time I'm on the big island. I've traveled to Oahu and Hawai'i so far and keep hearing how the big island is the best island... Pāhoa, Louisa's hut, and the numerous things to do, definitely add credibility to this statement in my opinion.
