My partner and I spent 3 night at the Volcano Suite. We were welcomed by the co-host, Leah, who has a wonderful, warm personality and was happy to provide some recommendations within Volcano and for other parts of the island.
The studio is comfortable and clean, and the surrounding is incredibly lush. This place provides an excellent retreat to a beautiful area. It also offers quick access to the downtown of Volcano where you can get a bite to eat or, if you happen to be there on a Sunday morning, go to the farmer's market and load up on fresh, local produce (highly, highly recommended). Hawaii Volcanoes National Park is a short 10-minute drive, and Hilo is about 45 minutes by car.
Note that this property is in a rain forest. It will be humid. Things might feel a bit damp, towels won't dry very quickly (or perhaps at all), but that's par for the course in a rain forest. Cleanliness can be difficult in very high humidity areas, and they've done quite well here. The towels and bedding were definitely freshly laundered before our arrival.
The continental breakfast was some instant oatmeal packages, fruit, granola bars, some bread in the fridge, and coffee/tea/hot chocolate. The fruit was not restocked after the first day, and we filled up the compost glass quickly (due to all the fruit we got at the farmer's market). This was not emptied until we asked about it after two days, so we had to use a compostable cup to contain the overflow; however, when it was mentioned to Leah, it was immediately addressed. The shampoo bottles in the shower were also empty. I feel I should mention these, but they were very minor points that did not detract from the quality of our stay.
Overall, this is a very nice property. It feels secluded and relaxing, but still provides quick access to the attractions of the area. Comfort and cleanliness were very good. I would recommend the Volcano Suite to others and would happily stay here again in the future.
