Don was very communicative. There was a plumbing issue with the shower that he actively tried to manage during our stay. He also had suggestions for places to eat.
Location was great, as we were close enough to the ocean to see it from the front door. It was also an easy five minute walk to Lava Java for breakfast (we loved the place), or Bubba Gump or a number of other restaurants.
Parking was not great. The place came with a parking permit, but it was first-come, and the tiny parking lot didn't have enough spaces for all the cars. The night of our arrival, we had to go searching for parking elsewhere, which was tough at night in an area we didn't know. We were about 50/50 on parking in the lot for the time we were in Kona.
Probably my own fault, but the place was smaller than I thought it would be, and the kitchen wasn't a full kitchen. Don had a hot plate and microwave, but we usually cook for ourselves half the time when we are on travel, which wasn't really possible. It would be enough to reheat a meal, or boil some water, but not much else.
