Sean and Zorro's place was quite unique. It is close to where you rent bikes/shuttles to go to see the lava flow at night, so if that is on your itinerary, this place is in a perfect location. I really appreciated and was impressed with how clean their place was! They take great care of the place and it was so nicely decorated inside and out!
I recommend coming to this place when there is still daylight out, as at night it gets pretty dark and hence difficult to find. In any case, Sean and Zorro were reachable by phone.
They provide towels. The shower and toilet are both outdoors (covered). You will have to be comfortable with using a composting toilet. There is plenty of drinking water provided in the refrigerator.
My favorite part of staying here: Waking up and seeing the sunrise from bed. Beautiful.
