I thought Accra was quite pleasant, never lived there full time but stops for a few days at a time. Yes it is easier to cope with over Nigeria, who wouldn't want that.
The city is not a bad place to be, quite a few things to do. Wasn't too difficult to get around concerning traffic.
I think the airport itself is quite organised, I always thought Accra ATC was one of the best in the region (well compared to the regions standards). Organising flight plans, fees etc, was an easier process than other African nations and the prices weren't as ridiculous as the usual ASECNA charges.
All in all, I would say this is good for Ghana, plus they have fairly reasonable growth. I wouldn't mind being based there whatsoever. Anyone want to hire me?
