We stayed here late April 2013. We originally booked the Big Grape property. We arrived to a sunset on the sea, and to a very friendly greeting by the neighbors in the Sea Grape villa. The Big Grape was nice, with two air conditioned bedrooms. Beds were excellent. There are two outdoor seating areas. From the upstairs balcony, you can see the ocean. You don't really get the sea breeze due to the beautiful gardens and trees on the property. We had Juicy make my wife her birthday dinner. It was delicious and comparable to pricing at most restaurants in Negril. We moved to the Sea Grape after two nights simply because the view from it is amazing, whether on the front porches, or in the main living room. The living and cooking areas are covered but open air, with no screens FYI - windows have louvers that can be closed. But the air conditioned bedrooms are all screened and mostly bug proof. There are three villas nicely separated on the property, and only two were booked when we were there, leaving it delightfully empty and quiet. We jumped and dove from the nice concrete platform by the sea, which has a sturdy access ladder to get out of the water - it's super deep everywhere here - 30 feet minimum. Two of the villas share a sea entry, and the other property has its own. There are jelly fish - we got stung by a few that were only mildly irritating. Once we rented snorkel equipment and fins from Negril Escape (next door), we always checked the water and avoided them. Morning water is calmer, cleaner, with more fish activity and less jelly fish. We snorkeled up and down the coast here, there really is a bunch of fish and beautiful coral. The coral cliffs have caves and crevasses making the terrain interesting. Water was turbulent in areas by cliffs but use common sense and it is safe - the waves were always very minimal.
Another piece of useful information is that you are expected to tip the staff that is there. There are three - Juicy is the host, cook, and go-to man; Bentley is the gardener and security; Christine is the housekeeper. They are all great, I found the housekeeper a little surly though which I personally don't mind. The property owner suggests 10% of your total stay gratuity, or "$5-$15 per day per staff member". Something to keep in mind while budgeting these properties. I found Negril expensive compared to other mostly third world locations, and everyone in the tourist industry is ready to milk every last possible cent from every tourist. From our other interactions and other hotel stays in Jamaica, most places don't demand or even suggest a tip for the staff. Know what stuff costs and stand your ground.
I highly recommend this place if you like the quiet, and aren't looking for the party scene - the main 7 Mile Beach aka Long Bay is the place for chaos, lots of party people, sand, and alcohol.
