This is truly an extraordinary place to stay! For us it felt a little like luxurious camping - instead of sleeping in the tent you sleep in a comfortable bed inside your own room in a wooden house, however you are still very close to nature and it only takes a step out of the door to see the beauty of the moon shining on lava fields or the sun setting behind the hills. There was one moment right after sunset when it was absolutely quiet (not even a chirping cricket was to be heard), which was an amazing experience. In general one has to be really quiet in this whole area - every sound feels way louder than elsewhere, as it is so quiet all around.
Beforehand we were a little worried about getting there with our small rental car (the last bit of the road isn't paved), however Lauren reasured us that it wouldn't be a problem and as long as you drive very slowly the car will be fine (just take into account that you need a little more time to get to the house than you would on a normal street).
There was only basic furnishing and equipment in the room itself (seemed a little empty) but it's very spacious and there is a lot of equipment in the shared areas that can be used, which is nice. Sadly our room wasn't very clean but otherwise it was very special and recommendable Airbnb especially for nature- and people- (as you can get in contact with the other guests very easily) lovers :)
