Dakar is a paradise compared to the rest of west africa - I've ferried various aircraft few a couple of times. Nothing complicated - nice easy ILS, plenty of parking, good ATC. Most aircrew stay in the King something or other hotel on the beachfront - I'm sure you can find it googling.
The only issue I had was that the local ground handling people were trying to insist that the aircraft wasn't safe parked on the south side of the apron at night, because the locals would come in through the fence, and "advised" that I should pay for a guard. Usual african rubbish...
