Recently I was traveling to Rwanda,In my experience Kigali is clean.
They have a visa policy that any one on earth can get an on arrival visa to the country.
Most interesting is the climate and beauty of the nature,They call the country ,Country of thousand hills.
When I travelled,it is the begining of August,people tell it's summer,but for me it was a cool climate.
The City and the country I felt has a business friendly approach. Seemingly corruption is less and people in the government offices seems to be very supportive towards foreign investors.
