We stayed at Shari's place for almost 2 weeks. We used it as our home while our home was finishing up renovations. It worked out great. The important things for us was having a usable kitchen, parking for both our cars and sleeping for the 3 of us. The kitchen didn't have a stove and oven, but the large fridge and induction burner made the kitchen completely useful for our family of 3. And it was very well stocked and clean.
The location across from Castles beach access was nice and it is walking distance to Aikahi Park/shopping area.
The only negatives for us were no access to a washer and dryer and also that Kalaheo Ave is a pretty busy street and not safe for our 3 yr old to ever be outside. Crossing the street to the beach was a slightly dangerous affair. But that isn't Shari's fault.
Overall, the place is well situated, very clean and comfortable and a great deal compared to most other options. Shari was very accommodating and helpful with things. Even though she was out of the country, she responded to things very quickly.
