There are lots of websites for non aviation information on expat life in Accra; accraexpat, has a forum and a helpful 'how to' guide of accra. There are many facebook pages for Accra expats, you can join and ask.
There is enough to do in the city, most of your social life will be at other people's homes. It's not the most vibrant city but its ok, safe and secure compared to the rest of west Africa. Some beautiful coastline and forests to visit if you drive a few hours out the city. It is expensive if you want to live like a westerner, I pay $3500 per month in rent for a 2 bedroom house
If you can't find enough information on the forums then feel free to PM me. Yes I am a pilot based here so give me a call if you ever end up here. Good luck.
