We had a great stay at Weng & John's. A few things to note about the place:
PROS:
-Incredibly clean
-Good Location close to Ko'Olina
-Free Parking!
-Well Appointed
-Great hosts
CONS:
-Futon, not a bed, so you roll off the edge
-AC needs to run all the time to keep it at a manageable temp
-The floor is a bit crooked, which is noted in the listing, but it takes a bit of getting used to
OVERALL:
It's a winner and you can't go wrong with staying with John and Weng. If you want to be by Ko'Olina or this side of the island staying here is a no brainer.
