Just returned from a fabulous time at Konrad and Robert's! It was as beautiful as the photos show, if not more so. Wonderful touches like fresh coffee, bread, chocolates, fruit, etc... Robert was very easy to contact and made himself available whenever we had any questions.
In the area, we highly recommend making it to the Sunday market. It was one of our favorite activities--and plan on eating lunch there too! Also, we loved Kehena Beach for relaxing on the beach (after a little hike down to the shore), the Kapoho Tide Pools for snorkeling, and Ahalanui Park for soaking. The Red Road was a very nice drive, and we took one day to go to Volcanos National Park, which wasn't far away.
The location is convenient to Pahoa and all of these destinations, but don't expect to be close enough to walk to anything. However, it was a quick, easy, and beautiful drive to each location.
We cooked each night and got groceries at the store in Pahoa, as well as Island Naturals. We picked up Thai take out one night that was great too. The kitchen at the house is fantastic, and we loved using the grill as well!
There was even a telescope (that we didn't quite know how to work), for seeing the lunar eclipse!
Lastly, we were traveling as a group of 2 couples, 1 single, and one toddler, and it was the perfect size. If you are traveling with a toddler, it is a terrific spot. The house is very safe and spacious for running around, and Robert even brought over several big boxes of toys. And if you get a rainy day, the TV has Netflix, etc.. and I recommend watching Moana (even if you aren't traveling with a toddler) :)
