We really wanted to love this hotel. The grounds are beautiful. We booked on the telephone and weren't surprised when the desk couldn't find our reservation (this is Haiti, after all). Next the desk clerk claimed she had no idea where the "simple" rooms were, as if the only guests she dealt with regularly stayed in the more expensive rooms. She made four telephone calls and found someone who could come to the desk to tell her where to put us. Thirdly, the clerk was very confused with our American credit cards. She had to ask more questions of other staff to find out how to process our cards, but finally was able to process both mine and my sister's credit cards. My sister noticed at the time that the clerk wrote down the 3-digit security code on the back of our cards, but assumed she did this out of ignorance so she said nothing.
The rooms were large and quite nice, but the bathrooms were a disaster. Every fixture that could be broken, was broken. The a/c didn't work in my room, so I had to move to another. The fixtures in this room were broken also, worse than the first one. There was no hot water in our room.
The dining was the best part of our stay. All of the meals were Haitian-style food, very good. The bar was simple but the service good.
The beach has very coarse sand and is small and narrow, but quite lovely. Salesmen hawking Haitian art are allowed on the property.
Our biggest problem came several days after we left Moulen sur Mer, when both my sister and I were notified that our credit cards were showing suspicious activity. Both our card numbers had been stolen and thousands of dollars of internet purchases made. We cannot be certain it was at Moulin sur Mer, but having seen the 3 digit security code written down by the seemingly confused clerk is highly irregular.

Love this place. Would love to go back.

This is the pearl hidden in a tough oyster! Enough said.

Stayed at Moulin Sur Mer on my last day of a mission trip also. There were 12 of us guys and we had completed a roof on a church building in Akakia(spelling), just south about an hour from Moulin. We stayed in PAP for the week but went to Moulin Sur Mer, people were great food was great, had air conditioning, felt very safe, as haiti unfortunately has much unrest currently. However, if you are in Haiti make it to this place cause you won't mind being there, nice beach, take a kayak and go to the point near the closed down club med, but Moulin is open and enjoy. I will be back Lord Willing next year to enjoy it again and best of all play water polo in their beautiful swiming pool. God Bless!
