Hey Ediwna,
Kisiizi is a pretty good place to do your elective at. I have lived in Uganda, and Kenya, but i promise you it is much more safer in Kisiizi than anywhere in Nairobi. It is cheaper too.
All you will need is to get ready to adopt to the people there. It is not hard coz alot of people speak English, but what you will need most is live a simple life and make friends with the people there. You will love it i promise you.
Am traveling to both countries this December
Best of luck
