We spent two days at the loft - the home was lovely, private, and well-maintained and met all of our expectations. Highly recommend going into Volcano and viewing the eruption before sunrise. We went around 5am, parked at the Devastation Trail parking area, and it was about a mile walk to the viewing spot. Only a couple other people were there this early - super cool!
Several hiking opportunities in the park as well - we enjoyed doing both Crater Rim trail - where you walk through the Kīlauea Iki crater and basically walk on the lava lake floor (about 4 miles round trip). We also enjoyed Nepau Crater Trail to Makaupohi Crater - about an 8-mile hike out/back. That one felt like a walk thru Mordor, and you get to see really awesome lava formations, steam vents, and a GIANT crater.
One note for future guests - there was no coffee at the house, so plan to bring your own. The two local stores where you can buy from close at 6pm and 7pm.
