Fern Grotto Inn is literally the best AirBnB that I've stayed in. The apartment was incredibly well furnished and tasteful, had everything you could want or need (it was literally a home away from home), and Paul was extremely friendly and helpful.
The welcome packet had great suggestions for everything from where to eat to which snorkel tours to take. Best of all, I was able to use one of the SUPs to go out on the Waimea river and paddle for hours - something that would cost ~$80-100 if I went through a company. Finally, the property has a number of fruit trees that Paul provides a fruit picker for - he walked me around and explained how to tell when things were ripe - the total Hawaii experience!
I will be back!
