Poipu Kai Kahala 533 was actually much better than the pictures originally conveyed. Yes, the decor is outdated, but the the unit itself was clean, incredibly spacious with high vaulted ceilings, large kitchen and bath, and had a good sized lanai overlooking a beautiful courtyard. The location is also perfect, enabling you to walk to the beach in five minutes, and there's also local restaurants (with great happy hours) within walking distance, including one right in the complex.
A few things to note if you are considering the unit. For those used to having A/C, the unit can feel particularly hot, especially in the living room area during the day. Other than the bedroom, we really didn't feel that the trade winds did much to cool the place down and the fans didn't offer much relief either. The bedroom does have an A/C unit, but thankfully was always a few degrees cooler than the rest of the unit so we didn't end up using it. Speaking of the bedroom, the bed itself is an old school spring mattress, so expect to feel and hear all your partner's movements at night; the bed is also very soft for those that prefer a firmer mattress. The bathroom also tends to get very humid and the existing fan struggled to help, so we ended up needing to leave the door open when showering. Finally, the wifi isn't great. The router is located in the bedroom and works great there, but it was difficult to maintain a signal in the kitchen or on the lanai.
One last nitpick, the kitchen is well stocked with the exception of two critical items: salt and fat (oil, butter)! Samin Nosrat would be appalled.
