What a fantastic stay! We really wanted to stay on the windward side of Oahu and Mata's place fit the bill. It was very clean, the beds were comfy, the price was right, there are some beach towels, camp-style chairs, a boogie board, and umbrellas that you can use. Each room has a fridge, a microwave, and a hotplate which was a HUGE plus. Laundry was really nice as well. It is shared but we didn't have any issue getting a few loads done. Communication was extremely prompt and the place is nice and quiet, a huge difference from the sirens and crowds of Honolulu. Fit 4 of us just fine. One of the rooms has a really big walk in closet behind the sliding mirrored doors (if anyone needed to use their air mattress, it would fit in there). Plenty of parking.
It is a little further south than it shows on the map, but that's a good thing. Only a couple minutes one direction to the Byodo-in Temple at Valley of the Temples and a couple minutes the other direction to the Waiahole Poi Factory.
During our trip we stayed at a hotel near Honolulu for two nights and at Mata's for five. We should have stayed at Mata's for all 7 nights. At the hotel we had a drunk guy in the hallway at 3am arguing with his girlfriend. At Mata's we had country silence. Easy to get anywhere and everywhere. And we did!
