Had a 2 day stay at Martinas while in Kona. The communication was easy and prompt and we felt very welcome. The cottage was how we expected it to be, a small place where you can spend the night, no more no less. Lovely hot shower and well functioning WiFi. The cleaning inside was good but the surrounding area seemed a bit messy.
Unfortunately we got completely eaten by mosquitoes just from walking from the car so we could not use the dining area outside and had to eat in bed but that is by no means the fault of the cottage.
