This is a wonderful condo (look at the pics!). Plenty of space, well appointed kitchen, comfortable bed, and pleasantly decorated. There are 3 ceiling fans and louvered windows to keep you cool. There is no ocean view, but the complex is right on Kiahuna beach (2-3 min walk through the grounds from the condo). Poipu beach (the most popular beach in Kauai) is 5-10 min walk, but honestly Kiahuna beach right in front of the complex offers great snorkeling and 90% less crowd, so you're probably better off just staying close.
The beach hut offers free towels, free chairs (non-folding deck chairs, deck loungers, etc) and other gear for rent, such as umbrellas, boogie boards, and snorkel sets for typical island rates. If you need a folding chair to take to another beach then you'll need to rent it some place else. The towels can be traded for dry ones as much as you like, which is really nice. They also offer surfing lessons and snacks, such as ice cream (!), for a reasonable fee.
This is a really big condo complex (~40 condo buildings, 300? units). It's managed almost like a hotel -- there's a 24 hour registration office that will give you your door key card, beach towel cards, etc. There's a restaurant on-site and a coffee shop right across the street, but the line was very long, so we avoided it. The hosts are in San Diego and were very responsive and seemed very nice from the messages they sent.
Bottom line: If you're looking to stay in the Poipu area, then this is a great place. Poipu is very touristy though, so if you're looking for a quiet, isolated island getaway, something a little more "off the beaten path" -- then you may want to avoid Poipu entirely.
