This place is great to visit Volcano national park, about a 10 minute drive away. It is also handy to go to Green Sand Beach and to Hilo and its surrounding.
It’s plenty big enough for two and very comfortable. Note that it is a duplex with the owner living next door. The place is very quiet and if the weather is good, the sky is beautifully lit with stars.
There is no real kitchen (no stove), but there is a microwave, a rice/pasta cooker and two (!) Weber gas grills outside, so planning for barbecue is a great idea. Note that the stores in Volcano village have a tiny selection so stock up before you get here. All in all, a good place to stay in if you want to see Kilauea and Mauna Loa.
