Absolutely great place to stay if you visit Pahoa or Hilo.
We stayed 3 nights at Konrad & Robert's. It seems that they renewed first floor as guest's space - modern and clean. I felt that Konrad & Robert prepared even very small things very well to stay comfortable. So we regretted just staying 3 nights there. Konrad & Robert are very gentle and kind, and they loved my children.
When I made a reservation, we were just needed the place to sleep, but after our arrival our thought changed. We spent a lot of time at their house. As like their picture, this house has a wide yard with many trees. My children loved their yards and their hammock, and they watched oranges and avocados at real trees.
At night we sat at the lanai's sofa and lighted a candle, and spent calm night time.
Especially it is recommend to stay at wide lanai on morning if the weather is good! you can watch rising sun and enjoy your own breakfast there. And don't miss their fresh fruits from their yards like oranges, passion fruits and avocados.
There are many places to stay and I've been stayed 5 different places (and now I'm continuing my trip..), but I think these places are more precious and valuable to stay comparing with numerous condos and vacation rentals, because it is real house people live and home like :)
