Mailing address

I now have a mailing address (sortof):
Attn: Piotr Brzezinski
Maxwell Court
PO Box 3477, Accra
#84 Forth Ringway, Ringway Estate, Osu Accra

Because there are almost no street names here -- my road being an exception -- there is no direct delivery of mail here. So the only way to send/receive packages is either going to a PO box, or sending it to a local FedEx / DHL office (which will hold it for local pickup).
