I have stayed in Poipu area many, many times; and in various Parrish properties.
Pros: This house is a short walk to Brennecke's and the beach at the Kiahuna Plantation. Nice big and clean pool. House pretty well maintained. Somewhat a private location, despite being on a small dirt road where people camped, fished etc. in front of the master bedroom.
Cons: Strange floor plan. The only bedroom on the ocean is the master. Three of the bedrooms had their own baths - two other rooms with king sized beds needed to share a full bathroom. Right next to this bathroom was a half bath which I guess was designed to be for the upstairs family room.
The internet was worthless. Dropped all the time and could not be fixed by the property managers, and they really did try. People who needed to do some work were using their phone hotspots - and were considering going to Starbucks. It was really bad.
There were cockroaches, and yes I know it is Kauai - but there were a lot of sightings.
Home was well stocked in the kitchen but there was no salt, or plastic wrap, or usual kitchen items that I am accustomed to see in these homes.
Clothes washer needs to be repaired as there was a lot of black mold (leave the door open!) Dishwasher was a hit or miss.
Our AC was broken for part of the vacation, which was a challenge for me. The owner should be making sure that everything is in better repair to avoid situations like this.
