I had an amazing time here! We requested a room with a bathtub and we not only got a HUGE bathtub, but the most amazing view we had during our entire trip. So many birds, geckos and wild (but not aggressive) pigs! I really felt like I was in the middle of a jungle while still being able to see and hear the surf crashing against the volcanic rock.
We stayed in Kai 6 and all the windows were just screened, so we were able to listen to the rain and birds the entire visit while enjoying the cool breeze. The cabin was surrounded by beautiful permaculture so privacy and human noise wasn't an issue.
I def say you need to have a vehicle since it's 20 min from town but there's a lot of beautiful spots to stop between town and Kalini. Also be sure to try the cold brew at the cafe at the entrance of Kalini, it was delicious and there's a lanai right behind the cafe where you can sit, see saffron finches and the beach.
They also do have Wifi that we could connect to when needed. If you're there on a Wednesday, go to Uncle Roberts for dinner and dancing. Bring cash.
It was a great time, we'll be back!
