A great place to explore the Volcanoes National Park. Situated roughly in the middle between Hilo and the park itself, Riaan's place lets you have access to Hilo and its amenities (we had dinner at Hilo twice in two days we stayed with Riann), but also be within a short drive to the Volcanoes, and also a lava viewing area from the Kalapana side.
The room we stayed in was spacious and very comfortable. There is both an indoor and outdoor showers (both with ample hot water). Bathrooms and common areas are shared, but Riaan and his family make guests feel at ease with this arrangement.
Overall, a great stay and an excellent value. Highly recommend, and would definitely come back. At last, a tip for the future guests: Ask Riaan about guided tours he offers.
