Wow what a unique place! The cabin is off the grid on a dried/cooled lava field. There is a medium sized central cabin with a living space and kitchen, with an outdoor bathroom attached to it, and a smaller separate sleeping cabin about 10-20 feet away. Both cabins are yours. Sean and Zorro have decorated the surrounding lava field with cool rocks and plants. This is not the type of place to be taking hour long steaming showers or expecting resort-style amenities, but you have everything you need and the space was very clean! You have working WIFI, hot showers, gas burners for cooking, fridge, etc. The bathroom is outside (without plumbing) but it was clean and didn't smell.
If you are staying on a Wednesday, you MUST go the the evening/night farmers market at Uncle Roberts! They have live music, delicious local food vendors, trinkets from various local producers, and cheap strong yummy drinks.
The only reason I rate this as 4 stars instead of 5 stars is because on our first night there, we came in on the tail end of a storm and the rain/wind on the metal roof was very loud and anxiety-provoking. If it wasn't for my ear plugs, I don't think I would have slept at all. Our second (rainless) night was wonderful! Keep in mind that this is something that Sean may fix by the time you are staying here, but maybe not. I would definitely stay here again! But do bring ear plugs in case it rains.
