We stayed at Mark's for 5 days in August. Surprisingly we didn't need to use the air-con during the night. We didn't get to see Mark, but his personal guidebook in the room was extremely helpful, and he generously shared his recommendations by texting during our stay. The location was convenient for our helicopter tour (Hilo airport) and lava tour (Kalapana), which were highlights of our trip. Most nights, we ate dinner at Pahoa, 10-15 minutes drive from Mark's place, which has one street lined with several great restaurants that we would not have known about if it weren't for his advice. Thank you Mark for such a memorable vacation!
