We stayed in at Rebecca's, in Poipu, for two nights while exploring the south and west side of Kauai.
We were not planning to be in the condo much since we were out and exploring, and the this rental more than met our needs for a comfortable place to unwind at night, sleep, and get going in the morning. Kitchen was well stocked with utensils and some of the basics, and the bed was comfortable. The condo was much more spacious than we expected, too, and would have worked for having a decent size group over for dinner (we didn't).
It is a ground floor unit, so it is a bit dark. Not a place I'd want to hang out in all day, but, as I said, it more than met our needs. You're also only about a 10 minute walk from Baby Beach and a little further for Lawai Beach.
If you stay and are looking for some good food options, there are lots of restaurants (local chains, etc) in Kukui'ula Village Shopping Center. Those were mostly higher priced than we were looking for (or lower rated), though we made sure to enjoy Lappert's for ice cream. Instead, if you exit the traffic circle and head north on Poipu Road, you'll quickly come to Da Crack and a sushi stand inside a grocery story; both are excellent. There's great shave ice at Loco Coco as well. Poipu Shopping Village has some other good options too.
