My wife, a Thai, and I stayed here for a few days after a week in Pattaya visiting friends. The missus had bought their VIP card for 1,000 baht/year earlier in the year, so we got a really good price on this trip: deluxe room for 800 baht/night, breakfast for 2 included. The hotel's front-desk lead speaks pretty decent English, so with that and a wife who's a native Thai speaker, communication with the staff was easy. The staff is also very friendly and helpful, and seem willing to make sure you have a pleasant and trouble-free stay.
The rooms are a nice size and very neat, with marble/stonework flooring. It's not a Marriott or Hilton, but it's not intended to be. Beds are quite firm, which with my bad back is a good thing, and the air-con works really well; almost too well at times. It actually got a bit chilly in the room at night so we needed to adjust the air-con to get it right; not a problem, though.
The location is close to a lot of other restaurants and markets, and is a short drive to the beach. Rayong is not a tourist destination, so the hotel caters largely to Thai customers, but non-Thai customers will still find this a very acceptable place to stay. We'll definitely stay here again.
