We had a lovely stay here - Hilo is great, and this place was just lovely, clean and spacious. The hosts were very accommodating - a fan for the downstairs room was broken and they replaced it right away, also bringing us a knife sharpener and some tea towels while they were at it. Access to the local beach was great - easy to walk down for a swim or snorkel.
We were comfortable enough at night with windows open (screened, of course) and fans on. I saw other reviews commented on the insects - Our first night there were some mosquitos in the downstairs (maybe from doors being left open by the last guests???) but thereafter it was just fine.
