The host was very responsive and accommodating, even for our last-minute requests. Although there is no direct beach access, it is a short walk to Brennecke's and Poipu beaches. And it's a short drive to Old Koloa Town and the Poipu shops.
The unit itself is a bit dated but everything was functional and serviceable. The bedrooms have portable air conditioners but they were loud so we ended up not using them. Having the windows open and getting the trade winds were enough to make it comfortable.
This place is definitely good for 4, but there were 6 of us. We intended to use the sofa bed but the mattress was so uncomfortable, one of us ended up sleeping on one of the foam mats.
