First off let me say that driving to treasure beach in Jamaica is a bit of adventure itself. Jamaicans are not big on road signs/ fixing pot holes which led to both a flat tire and couple accidental side trips on the way to the villa. It's nice to have a car in Treasure Beach, but be aware that it will take about 3 hours to drive there from Montego Bay and it isn't the easiest place to find until you get to know the area.
Paolo for whatever reason refuses to accept payment in any form other than wire or cash, which made me very wary of dealing with him. However, he is legit and he is super nice. He helped us get our flat fixed and went out of his to make sure we had a great stay. I trust Paolo 100% now and wouldn't hesitate to wire him money, even though some people might not want to do that.
The house itself is great. 3 Bedrooms, each with it's own bath and one of the rooms has two beds. AC in the bedrooms to stay cool at night. Kitchen is well equipped, and the living room is comfortable. The interior roof of the house is just unfinished wood which is kinda funky-cool, but also looks a little shabby. Monica was the housekeeper/chef for us and did an amazing job, her cooking was some of the best I had in Jamaica. The house has a wonderful porch for lounging and is right across the road from a great beach. Locals come to this beach because it is somewhat protected from the waves by a reef and is very calm to swim in. You can also walk around and explore other beaches in the area, but we spent most of our time at the beach right across from the house because it was that nice (though it isn't a large beach- it's surrounded by some rocky areas on both sides).
Paolo also graciously offered to pick up groceries for us in the big city before we got there to get things that hard to find locally and save some money. There is a smaller grocer in TB that has most anything you could need though. There is no ATM in TB.
We discovered about 3 cockroaches in the house while we stayed. Not a big deal to me, but that might be a big turnoff for some. Otherwise the house appeared quite clean and well kept. One night a cat (we think) somehow opened a partially closed screen and grazed on some of our bread. Perhaps he let in some cockroaches too. The power went off temporarily after a storm, but Paolo has a generator he fired up for us and the power company had it fixed in a few hours.
Overall I think this house was great value, and I would definitely stay there again.
