I love it when folk are in denial after reading an erroneous headline, in spite of the evidence.
One can only assume that you are a troll-fol-de-rol.
I live on Samui and I have been to that area a few times.
It is not a hotel. It is a coffee shop with a few rooms to rent as shown in the photo that has been posted earlier. One can also see it on Google street view. (Difficult to fake that!)
Booking.com sells more than hotel rooms, but most of their customers assume a hotel. Some of our customers advertise their private homes on Booking.com
The Brit guy could not find the 'hotel' but he was more angry with Booking.com for being slow to refund the money for his second choice when they told him that it was full and he had to pay for a third choice.
But hey, stay in the dark if you wish.
