I dont...
But I have had people working/living in Conakry in support of a customer we have since about 2009...
If you decide Guinea is somewhere you want to go, let me know, and I can put you in touch with a guy that has been there for several years.. who could probably tell you anything/everything you would want to know about the country..
FWIW, Guinea can be a difficult place... It aint SA, Namibia, Tanzania, or even Zimbabwe for sure.. it presents far greater challenges for our people that work there in many ways than our people that work in the Central African Republic, South Sudan, and even Somalia (other very challenging places to live and work)..
