Pros -
Maria was friendly, generous, and accommodating (we arrived much earlier than the check-in time and she graciously allowed us to drop off our luggage ahead of time)
The entire space was clean, airy, and welcoming
The bed was comfortable
The lanai in back had a mini fridge, microwave, sink, etc.
The space is on a quiet property, conveniently located ten minutes from the airport (you can't hear the planes, though), just outside Hilo, and across the street from the ocean

Cons -
None!

I would definitely recommend staying here.
