I have only good things to say about Soon's place.
The room was very clean, well prepared, and the bathroom was well stocked with all the toiletries that we might need: new toothbrushes, toothpaste, a TON of towels, bar soap, actual shampoo not weird hotel stuff ... etc.
There was a box of chocolate waiting for us, which was without a doubt a nice touch.
The hotel's location is great: ~3 minutes walking distance to the convention center, and ~5-10 minutes to the beach. This was perfect since I was there to attend a conference. But even if you're just going there for vacation, I think it's still a good choice.
The hotel has a nice pool, fitness room, a starbuck's, and a nice breakfast buffet place, so it's very convenient.
Since this is a privately owned room inside the hotel, you don't have housekeeping service, but that's to be expected, and wasn't a problem for me.
All in all, if I'm going to Hawaii again, Soon's place will definitely be top of my list.
