Mary's place is utterly beautiful. It is secluded and offers complete privacy, yet it is easy (15 mins) to get to stores and restaurants in Kona. Mary has left some very helpful amenities like coffee, tea, snorkels, sunblock and, for us mainlanders, aloe vera :)
We loved the frog songs at night--but note that they are quite loud so if you are sensitive to wildlife noises, ear plugs, white noise app, or a sound machine might be useful.
We had a wonderful experience staying here and loved every moment. Thanks, Mary!
