My wife and I enjoyed our stay at the Mariner Cottage but there were a few communication issues that prevent us from leaving a 5 star review. The cottage is a good base for adventures in Volcanoes National Park. We enjoyed listening to the coqui frogs at night, and making friends with the cute geckos and bullfrogs that paid us a visit during our stay. If you like nature, you'll feel at home here.
Communication with Jaecob was great initially. He responded immediately after we booked the place with a few different driving routes we could take since we were flying into the Kona side of the island. After those initial messages though, he didn't respond to subsequent questions we asked before and during our stay. I messaged him through Airbnb the day before check-in to ask where to find the key since he instructed us that the house would be unlocked and to simply let ourselves in. He never responded. Later, we found that we had only been provided a single roll of toilet paper for a four-night stay. I messaged asking if he could bring more, but Jaecob never responded. (The nearest place to buy basic supplies is a 20-minute drive.) Since he didn't respond, my wife and I bought a pack of toilet paper the next day when we were out in town. When we returned to the cottage at night, there was a roll of toilet paper waiting for us on the lanai. If Jaecob responded to our message and let us know he'd bring a new roll, we wouldn't have needed to make a special trip to the store to buy some. Pretty frustrating.
