We loved our stay at Papakea! It's located at the northern tip of all the obnoxious Lahaina resorts, so you're away from all the chaos, but close enough to enjoy all the amenities/restaurants/destinations within walking distance. Having a condo so secluded and beachfront was priority #1 with us and this place totally delivered. Extra bonus because the kitchen has a blender.
My only point is to read all the fine print before booking. A $149 a night condo is a dream come true in this location, but paying for a $255 cleaning fee for 4 nights/2 people is kinda a bummer...as is having to pay extra resort amenities outside of AirBNB. Think of it this way before booking - there are four parties involved in this reservation taking a cut of your money: the condo owner, the resort, AirBNB and the third party company hired by the condo owner to rent it out.
Overall, the price is on par, if not better, than everything around us. Just read everything and know what you're going to need to pay beforehand. It's all written out.
If its in your budget, this condo is a perfect weekend paradise retreat for two.
