Here is an honest opinion of the house. We stayed there for a week in March of 2018 with our family of 5 (2 adults and 3 kids, ranging ages 5-8). The house is in a wonderful location at the end of a private neighborhood towards the end of Kailua on Lanikai beach. This is the most beautiful beach on the island and one of the top rated beaches in the US. I would highly recommend staying in Kailua and spending time on Lanikai beach.
With respect to the home, it is fully stocked (toilet paper, paper towels, beach supplies, beach towels), cable TV, decent WiFi, Washer/Dryer and central air which is hard to find on the island. It is about a 15 minute walk to the beach, so we drove each day. It is about 5 minutes to the ocean access, not beach access. Parking was fine. Greg was responsive as an owner.
Here are some of the cons. The house is dated and needs about $50k in repairs and updates. The kitchen is made of formica, the carpets downstairs are worn and had areas with excessive breakdown/stains, the guest bathroom had been glazed which was wearing off that no one used, and we had regular cockroaches in both the garage (large) and kitchen (small to medium).
The house has tremendous potential and is in a great location with a good layout / view. It just needs a renovation and a regular exterminator.
