I am retired in Ghana and can recommend it as long as you have sufficient money for a reasonable standard of living and a good support system and are fit and healthy.
No I've never been to Ghana. I've been to Burkina Faso twice and Cote dvoire once. I'm retired now and living on a very modest fixed income. How is Kumasi?
I like Kumasi it is cooler here and a bit cheaper to live I think. Accra is more cosmopolitan and over populated. You should take a trip before deciding.
