We spent a night there last month, beginning of low season. We were the only tourists, the place looked desert.
The bungalow was nice, modern, clean, with a roofed terrace, view on the lagoon (well, a lake).
The 2 staff we met were very helpful and smiling, they do not speak English a lot but that was enought to communicate. The manager , who speaks English, was reachable by phone if needed.
We ate there, but they did not have everything displayed on the menu and we did not get everything we ordered in advance. But we were served on our private terrace, which was far better than in the empty restaurant.
We borrowed a tandem (for free, I do not know if this is always the case) and went to discover the surroundings. There is not much to see, some small villages, no local restaurants and a few shops (beer, crisps, soap..)
Breakfast was also served on our terrace (toast, butter and jam, egg and sausage, coffee or tea), very good.
The swimming-pool is also very nice, clean.
I would recommend this place, but maybe not for more than 1 or 2 days as there is almost nothing to do there.
We were driven back to Udon Thani center for free, it takes around 20-30 minutes if I remember well.
