I have stayed here 3 times, and while the grounds are lovely, and the staff friendly, their booking system is a mess, and the maintenance of the resort is worse.
Even though I always book and pay in advance, they always have difficulty finding my reservation.
However, on my last visit, there was also a problem with the electricity. There are often electrical outages in Ghana, but they could not get the generator to work, and so our rooms had neither electricity nor a/c for either of the 2 nights we were there.
Given this track record, I would say: proceed at your own risk.
