We stayed at Steve's for 2 nights and loved everything about it. The location is perfect, and the house is gorgeous! I actually think the pictures don't do justice! The place itself is more amazing and tastefully styled... The lanai was absolutely the best (of all 4 airbnb places we stayed at in the Big Island). We're already planning our next visit!
Steve himself lives upstairs and is very quick in responding to messages.
One thing to pay attention to is the extra ~14% tax that renters have to pay separately (there will be a separate email on that after the reservation is confirmed). It is clearly mentioned in the house description, but I hadn't read it carefully and was a bit surprised when I found out about that.
