We stayed at Judith's place for about 5 days and it was truly wonderful. Judith was super communicative and friendly from the start. We ended up arriving a little earlier than anticipated and she was very accomodating. The location is close enough to all the beaches and restaurants and bars but just far enough to retreat to a quiet spot when the day is over. The views were stunning! The bedroom was nice and big and quite comfy. We enjoyed using the second outdoor bathroom and the pool as well. Because it's at a slight elevation, it was fairly cool and pleasant at night. A nice respite from the heat of the day. Bill was super friendly and gave many great suggestions for beaches and restaurants. We also enjoyed having access to beach supplies like beach towels, snorkel gear, etc. Overall, we had a fabulous time exploring Kona.
P.S Don't forget to stargaze at night. It's a great spot to look at all the stars!
