The Mary’s condo is ok. It’s well located in Kona (not far from few restaurants and close to safeway) but the unit is near the road and can be noisy at night.
The futon is for only for a kid and not super comfortable. 4 people cannot be on the lanai at the same time.
Having that said, the king bed was comfortable, the condo is really well equipped and super clean. We were welcomed by Kelly who gave us good tips on the Island. We had some WiFi issues and Mary was super responsive to get it fixed. The pool is awesome and the sunset from there too.
