This is a fantastic place if your aim is to have downtown in walking distance. Ali's building is probably the closest and nicest that you can find! It's got everything that you might need, and Kim and Ali are very responsive.
One tip for a walkable Kona: you'll still want some sort of vehicle to explore a bit, since Kona / Ola Brewing, etc is still 20+ minutes away. We rented mopeds for the weekend, which made things easier.
