Great space.
The second floor apartment has great cross ventilation provided by multiple large windows. There are many ceiling fans to keep you cool even without AC. The queen bed is very comfortable. The kids were on the sofa bed in the living room. There is a coffee maker, filters and even ground coffee provided.
The check in instructions are easy to follow. I really liked having off street parking and a gate. The guest house is separate from the main house, which I really like. This is a great place to stay while you are on Oahu.
