I recently spent 4 nights at Seaclusion with a group of 8 persons and it was absolutely perfect for my purpose.
The host (Manisha) did a great job giving directions and information about the property before arrival and she was there to greet us. The property has a locked and secured gate and has parking for multiple vehicles.
The house itself consists of 3 bedrooms (all of which air air-conditioned) and 3.5 bathrooms, which helps when catering to a larger group.
The kitchen itself came with pots and pans and some basic supplies and spices. You will be required to bring your own food etc.
The dining room table was adquate to fit my group and the house has more than enough sitting areas.
It has to be said that the real highlight of the property is the view from the various balconies/terraces. We would spend literally hours sitting looking out to the sea and relaxing to the noise of the waves and the occasional passing boat.
There is access to the sea, but the waves were unusually large in Jamaica this Christmas, so it was not utilised by my group. When the seas are calm, I can see it being a great place to snorkel (as it is a protected conservation area).
Overall, we had a very good experience at the house and Manisha was easy to contact and get in touch with for any of our various queries.
I would recommend it for larger groups who have a budget to adhere to and want to feed/take care of themselves with minimal interruptions.
NB. I was told that there is a caretaker/gardiner, but we did meet him, possibly due to the it being the Christmas holidays.
It is also worth noting that there was no kettle at the house for my stay, but I was told this ahead of time and brought my own.
Seaclusion is only a short drive from the centre of Ocho Rios which is great. The view of the ocean from the porch is just incredible very scenic great photo opportunities. There also a path that goes down to the water which provides a nice secluded spot to relax. It's the perfect size for a large groups and fits 10 easily and it's the best value for size. 10/10 would rent again.
