The upper unit has an open floor plan and is meant for a single or couple, with potentially another single or couple (or two singles) downstairs. The stairs connecting the units is on the exterior of the building, which provides additional privacy. The upper unit has no window curtains anywhere which may be a concern for those who may require a bit more privacy or who want to sleep in without being awakened by sunlight streaming in. The lower unit has window curtains and a bed that can be utilized as a queen-size or split up into two single-size beds. Regardless of the coverless windows in the upper unit, we did feel like there was enough privacy as we could not see any neighboring houses in any direction except on the adjacent lot where there is a house that appears to be abandoned or not lived in anymore and slowly being taken over by the jungle. However, if you don't like being in a potential fishbowl, then maybe that is something to consider.
The craftmanship and woodwork in the upper unit is impressively done as shown in the pictures. If it is cold, there is a gas stove to heat the upper unit. The deck on the upper unit is a nice place to hang out until it gets too cold, usually in the evenings. Volcano is situated at a higher elevation where the temperatures are lower than Kona and Hilo.
Over all, we really enjoyed our stay, we enjoyed the beauty and design of the upper unit, and we were sad to leave!
