Bujunbura
Lovely place.
Before arriving review your plate well. Lots of high ground in the area.
As far as Buj goes, French speaking, but can get by with English. Plenty of taxi's at airport, locals are very friendly. If one or two nights stay at Novel Hotel, it is central and not far from airport (approx 10 kms) good Chinese Restrant across the road. I spent 5 years there and loved the place, plenty to do over w/ends.. the lake is beautiful and clean with crocks and hippo's... Suggest don't go swimming! Sorry I am not with you!
