This unit was awesome for our 10 day stay in Kailua. Very convenient location and the unit is newly updated and has everything you need. The only thing I wish it had was a few more places to hang bath towels in the bathroom. There was only one rack. We had four people, so this was a continuous problem. Something else to note that has been mentioned before is that the wifi was pretty bad. We had trouble streaming anything most days, which is a bummer when on vacation.
The biggest issue was that the adjacent neighbors are young and like to hold VERY loud parties. It was great for the first week of our stay, but they had a large number of people over the last three days of our stay and they played loud music all day and late into the night (3am), with lots of shouting and screaming. The walls are very thin, so this was extremely frustrating. We finally went over there the second night and asked them to keep it down, which they did a bit, but it was still enough noise that we had a hard time sleeping that night again. Bring earplugs for this place. If the neighbors don't keep you awake, the roosters will :).
I try to be fair in my reviews. I know that the host cannot control the neighbors, but I would want to be informed about these kinds of things if I were to stay here in the future.
