My husband and I stayed at the Green Bamboo cottage for 4 nights the first week of March. It is a comfy studio for 2 people with a functional kitchen that we used every night to cook our meals. Be aware there is no microwave in case you want to warm up prepared meals. There is an oven though that was great to cook our fish! The bathroom is nice.
Be aware you'll be staying in the Rain forest, so it is very humid outside and inside the cottage as well as you need to leave the windows open to get some cool air. If you're not used to or don't expect it, it could surprise you. Nothing will really dry and your dry clothes will get humid. We stayed in March so maybe it's normal for winter season.
The property is really nice, no sounds other than the coqui frogs and birds. If you like silence when you sleep, bring some earplugs. I found the sound relaxing! The cottage is well located if you want to go to the Volcano park, see lava on the shore or go to Maunakea. Our hosts left good recommendations and instructions for staying on their property. You can pack your bags now ;)
