First thing - the property was clean - esp. the bathroom - made a whole lot of difference! No insects or roaches - which was the case in other places we'd stayed in Oahu and Maui. Next, the kitchen - lots of pots, pans, cutlery, plates, etc. Next - communication: Gerry is prompt in responding and resolving the issues. We didn't meet him in person, but it wasn't necessary, he always responded :) About other positives, the Hawaiin Princess property felt very safe - all entry/exit are secured and require key.
While there is a 24x7 security guard, during our stay, the area in general felt safe. The people we met at Grocery store (Tamura) and at restaurants nearby were friendly and welcoming. Yes, there are homeless people by the beach, etc., but they didn't bother us. They didn't wander into the beach area of the property either. Though the beach is open to public, it seemed private - only folks from the properties seemed to be using it.
Only minor thing was the day-bed - wasn't comfortable, after emailing Gerry, discovered the airbed, which was way better.
And, oh, the commute - since Makaha is on the West end of the island, and most of the places to visit are on the Windward side, you will be driving a lot - through school zone with speeds of 25mph, though the locals don't seem to follow it that stritcly :) Then again, it is Hawaii, so if you take it easy and relaxed, and you will enjoy the drive too.
When we visit Oahu again, we will definitely stay here.
