True to its name, Affordable Hawaii offers an inexpensive perch from which to explore the South Kona Coast. Come share ex-California resident Nita Isherwood's century-old 4-acre farm, which is overflowing with macadamia-nut trees, coffee, tropical fruits, avocados as big as footballs, and even jaboticaba, an exotic fruit that makes a zingy jam and local wine. The least expensive room is inside the old farmhouse (hey, at $70 a night, this is a deal!). The Greenhouse wing has two rooms with wooden floors, big windows, and private entrances. The most unusual accommodation is the old coffee barn, updated into a rustic room for two with a raised queen-size bed, a fabulous view of the coastline, and an outdoor shower. Guests can use a common kitchen with a refrigerator, microwave, hot plate, and barbecue grill.
