I have visited Accra for business purposes, and I have stayed in BEST WESTERN Premier Accra Airport Hotel with my collegues. I have stayed in a premier room, which is large with good quality king size bed. Room was clean and comfortable.
On the other hand, one of my friends saw a lizard in his room, and some of the collegues have seen cocroaches in the rooms. I think, if there is any food in the room, cocroaches and lizards visits your room :) If you do not keep anything in the room, and call room service to pick up your tray after the meal there will not be any problem.
Room service is fast and good. In the restaurant, please do not expect any standard. I have ordered mushroom soup for 4 days. First 2 days it was very delicious with sliced mushrooms inside, in the rest 2 days it was as liquid as water with chicken smell and no sliced mushrooms inside. One day I have eaten a steak which is very delicious, the other day it is not possible even to chew. Staff is very slow, for a coke you can wait 15 minutes. If you complaint about the food, they try to fix it.
In overall, hotel is ok for Ghana. It is clean unless you keep any food outside the refrigerator. Gym is ver small, pool seems ok.
