The stay at Janelle's was everything we were hoping for and a lot more. I really wanted to go to the farm, my friends were a bit reluctant about it due to some of the other reviews on airbnb. I can assure you that Janelle's farm is very clean, everyone working there is extremely nice and tries to take care of you as a person not just a costumer. I'd say with this airbnb you should just really ask yourself if you want an authentic stay at a remote farm on the Big Island or you prefer a mediated, touristy experience. If you want the latter, you should go some place else.
We did not encounter roaches, even though roaches are usually everywhere on Hawai'i. It was very clean, the room was amazing, it was no problem that the charging station was in the common area. The shower was charming and clean, it's amazing to wake up and just shower in the jungle.
I would recommend this place to anyone who is tired of Waikiki, but if you expect a resort you should go somewhere else. I loved it and if life's gives me the chance to do so, I would definitely come back.
