Did the tour with a lovely guy called Joshwa and the organisation Kibera Community Empowerment Organization (KCEO). They are doing a lot of things to help improve Kibera and they are doing the right things and they seem to be working.
It is a good tour, they help you get there on public transport, and they take you around Kibera(you feel safe there) and around to some of their projects. It takes about 2-4 hours. Would really reccommend doing this. I have added their website below if you want to book a tour, they are flexible with dates and times.
