Place was as described - clean and in a great central location to get around Hilo. Communication was fast and clear, including good directions for arriving and entering. The apartment itself definitely gets warm during the day, but cools off quickly at night as soon as the sun goes down. Only potential warning would be for very light sleepers. The entire complex was pretty obviously converted from a resort at some point in the past, so the unit is built and insulated more like a hotel room. This didn't bother me, but those used to ultra-quiet places will definitely notice their neighbors.
Only issue for my stay had to do with check-in, but that was entirely my fault due to having not fully updated my Airbnb personal information recently.
