Brads place is very nice with a fun backyard area to BBQ, hang out and even play some volleyball. I would highly recommend it to a sporty family or group of friends. Two of the showers are part of the 2 master suites leaving only 1 shower for the rest of your party. If everyone is willing to share then there are plenty of places to get ready, but if you have people that value their privacy then it could get cramped.
The house has a nice main room with a flat screen TV right right next to an extremely large kitchen including a bar and kitchen table to sit and have your meals. The leather couches seat 5 and could recline, but don't as they are not connected to a power source. This bummed me out a bit :).
No air conditioning, but lots of ways to keep air circulating as there are ceiling and standing fans all throughout the home. We slept on top of the covers for the majority of the nights, so if warm nights is a major concern be prepared. My wife runs cooler than me and was able to sleep under the covers with no problem.
House has some great views of the waterfalls from the mountain, but you can only see them from the front of the house and there isn't any real easy way to sit and enjoy them.
Location is on the north side of the island, which is by far the most beautiful side area on Kauai there is lots of rain here but not enough or for long enough to be considered a negative to this location. We loved running along the golf course or down to St. Regis to take in the views in the mornings. Some of the excursions can be a drive, however the drive is so nice that it makes the time in the car worth it.
Ultimately, I think the house is great for sporty groups that can utilize the backyard. It's a little overpriced, in my opinion, as I feel like you're paying for the neighborhood more than the luxury of the home and if you are like us and plan on spending most of your time out enjoying the island the neighborhood didn't seem as important to pay for.
