We had a nice 3 nights stay at Kj’s cottage. It’s clean , cozy and easy access to Kona. The only draw back was the roosters. They were loud in the early morning ( 4 am). We were warned about it going in. So if you are a light sleeper, it may not be good for you.
Kj is a very good hostess. No problem with checking, she replied to my questions promptly, she has nice recommendations for dining and activities.
All in all , a very nice place to stay.
