Dear Shinny,
I'm planning to go as well in Kinshasa. But I already went there and got many infos about the life. Your salary is enough to survive in Kinshasa. Regarding the transportation, if you could have a car, it could be very easier for you because the public transportation is very very difficult in Kinshasa, but at the beginning, just use the taxi or even the moto taxi ;-). The majority of UN and organizational institutions are indeed located in Gombe. But Gombe is also one of the mist expensive area to live, specialy if you are located in the city center. I could recommend you some plare in the neighboroud of the city center. Lastly, Kinshasa is a safe city, but like every cities, there are places not so safe. So, as you are expats, I do not recommend you to walk around alone in some areas during the night.
Cheers,
EJ
