This Airbnb was nothing short of amazing. Robert and Konrad did such an amazing job with this little apartment. It sits right below their main place of residence. I'll go into a little more detail because the pictures and description don't do it justice.
The bedrooms are spacious and very comfortable. The bathroom was also large, very clean, and stocked with soap/shampoo/conditioner with the benefit of having an extra outdoor shower that was also fun to use. The kitchen was quite small but still large enough to do what you needed. The highlight of the apartment was the outdoor porch area, which is extremely large and opens up to amazing views of their backyard (which was filled with beautiful tropical plants/fruit trees) and the southeastern Hawaii landscape. You're situated next to the 2018 lava flows and there are open fissures close by that you can also check out. You feel like you're living next to Earth that's being created and in flux (because you are!).
Robert was extremely kind and greeted us when we arrived at 9:30 pm. They have a notebook in the apartment describing the rules and what to do, along with recommendations for nearby attractions and restaurants. We decided to follow their recommendations over some of our own (Pohoiki Bay hot springs near Isaac Hale Park) and don't regret it. We also took advantage of the abundant fresh fruit growing on their property for breakfast and snacks, although some fruits might not be there depending on when you decide to stay. Also note that there was no air conditioning (something that is apparently common in Hawaii) but we felt comfortable the entire time, mainly because the weather on this part of the island was perfect. We found that using the provided fans and leaving the windows slightly open (with bug screens) was just enough. There are also lots of coqui (frogs) in the forest and chirping at night, but it wasn't distracting. In fact, with the windows slightly open, it was a very relaxing sound. The resident outdoor cat, Zeus, was very sweet and loved the extra attention we gave him.
The fridge was stocked with plenty of supplies as soon as we got there (coffee, bread, eggs, creamer, condiments, fresh fruit, etc.) and saved us a trip to the grocery store, which we greatly appreciated. In fact, this place was so nice that we decided to get rid of some of our morning itinerary things in order to spend more time here, which we don't regret doing. If you're planning to spend most of your time on the West coast (i.e. near Kona) then it might be better to look for something else there. However, if you plan to spend your time on the East and/or South part of the island, road tripping, in Hilo, or at Volcanoes National Park, then this should be your first choice. We even visited the Mauna Kea summit and picked up dinner in Hilo on our way back and didn't find that it was too far.
Overall, this Airbnb was an amazing experience and by far the best we have ever stayed at. I would 100% recommend that you consider staying here. You will not be disappointed.
