Linda's downstairs unit is well appointed, spacious, convenient to Volcano town and the Volcanoes National Park. There was a family of 5 that was renting upstairs as well at the same time which was fine despite the rambunctiousness of the 3 boys.
We mostly spent our time exploring the Park and got food in Volcano. When we did eat at the unit, there was enough to prepare light meals in the kitchen with fridge, hotplate, microwave, and toaster oven. The kitchen was clean and had all the necessary utensils, and dishware.
The bed was comfy. The bathroom was good, complete with towels, shampoo/conditioner, and body wash. The TV was nice and came with a media streaming Roku stick which was connected to good internet.
There was a rumble of mechanical sound that came from behind the house periodically which seemed to come on more often when we were using the water. My guess is it's a pump for the water and it largely stayed quiet when we were sleeping but was at times noticeable.
We also noted a smoke smell (or something like it) in the room which bothered us a little since we do not smoke. We attempted to air the unit out but that did not improve the smell much. This may not be an issue for you but it was noticeable to us.
Note that there is a gas fireplace in the living room but it did not turn on. There are, however, plenty of blankets and it warms up during the day so that's not so much an issue.
The yard was tropical and the place lived up to its rainforest designation. There was a well marked driveway and parking for at least 2 cars.
Overall we had a good stay. The location was good, the room was good, check-in and out was easy, and price was reasonable.
