Margarita & Kevin's house is really good and cozy. It is quite small but everything I needed was right there; lots of kitchen tools, tablewares, seasonings, washer & dryer and even many DVD for kids.
And the manual for staying was well-organized and helpful.
Location is also good. It just takes 10 mins. to Hilo downtown.
When I had a problem with power, Kevin went right away and fix it. If you need any trouble to stay there, then he will definitely help you. :)
