I traveled to Big Island with my family and ended up running into issues with our lodging near Hilo. I found Yumi's listing and booked it on a one day notice. Yumi and Gen were both very accommodating and even suggested places around Kona when I let her know that we did not have any knowledge around the Kona area.
The house was very clean and comfortable and there were plenty of clean bath towels as well as beach towels. It is within a few miles from the beach and there is easy access to a lot of the major attractions in Kona.
Overall, I would book again if I am coming to Big Island.
