We loved staying at Naomi’s house! It is a beautifully decorated and comfortable home. It was very clean and nearly everything you need is provided, including shampoo, laundry detergent, and there was even coffee and some other staples in the pantry. The evenings are gloriously quiet and cool.
I recommend you get groceries before coming into Volcano - the two markets close fairly early, and while there are several restaurants in town, many close on certain nights during the week and others book up early (or days in advance for the restaurant at Volcano House).
