A clean, well located and high value (i.e. relatively cheap) place that we enjoyed to stay. The house is not new - it is probably an old house, but it is very well maintained, and clean, and bug free (which is not that easy on Hawaiian islands).
The location is very quiet overall, yet not far from the downtown (Hilo is a small town after all). Quiet from cars and human noises, but there will be animal sounds. Most noticeable is the coqui frog at night (google it), but no one can escape their sound at east side of the big island, and the sound doesn't bother me (ear plug can help to some level). One early morning there was a rooster crowing loudly close to the house. That did bother us but we don't blame the house and we eventually considered it as part of the "fun" of the trip. The take away - ear plug is your friend.
There is just one small air conditioner in the living room, plus a de-humidifier. There are ceiling fans and standing fans all over the rooms, and the house is well ventilated. Over-all we didn't feel too hot while staying in the house in June.
The hot water is a little under powered. It is good for one person taking shower but struggle to power two showers simultaneously.
Overall we highly recommend the house. It is not perfect, but it provides great value and a comfortable stay.
