This was a great place to stay in Kona. The unit was easy to access, clean, and comfortable (note that the AC doesn't reach the bedroom, but there are two fans). We loved the poke shop across the street, BBQing on the grills overlooking the ocean, and exploring the tide pools where we saw a couple turtles. There's some snorkel/swim gear in the unit, and plenty of kitchen supplies (rice cooker, blender, plenty of pots and pans, etc). Laundry is shared coin laundry near the lobby across the street.
We received clear instructions from Vacasa although the experience isn't as personal as a typical Airbnb. We had everything we needed, so can't speak to their responsiveness with issues. Overall I'd recommend this place - it's a great value and decent location!
