My girlfriend and I stayed at Melissa's place for one night. We enjoyed the rustic charm of the cottage, and it certainly is in a very beautiful and unique location surrounded by a sea of volcanic rock.
The location is quite secluded, which we enjoyed. It is within 20 minutes of Pahoa if you are interested in grabbing a bite or in need of groceries.
Melissa was prompt in her replies to a few issues we encountered and was very polite and fair in addressing the issues. She also gave us a helpful heads up about the front door prior to our arrival.
A few things we wanted to call out - we're not sure if it is the norm, but it was windy the night and following morning we stayed... very windy. In these conditions the cottage is very loud making it challenging to sleep, but once I put on my noise canceling headphones all was well. Additionally the door has a few issues due to being slightly misaligned with the house frame which Melissa told me were being addressed.
All in all, we enjoyed our stay at the Blue Lava cottage. It is a very unique experience and if you're in the area it's worth checking out.
