I spent several weeks in Mombasa in 2002, right on the coast. The wealthy parts really are, security compounds, plush beachfront villas with private beaches etc, but the rest of the city was really (and I mean horribly) deprived, people living beside the road under sheets of corrugated steel, with their family goat tied outside. I saw people syphoning grit-filled diesel from a tanker crash just to get some light in the evening.
Having said that, the people are massively friendly, although we were told that being a big muslim country, there was a terrorism risk. To me I never felt that there was any danger to us, except when our 'scratch' cricket team lost to the Mombasa select under 15's!!
The weather was great, storms you could set your watch by in the evening, but fabulous to watch.
The locals at Mombasa airport could not do enough to help us, even going so far as to chop down loads of trees around our line hut with their machetes, as they had spotted a green mamba (snake) hiding in them. Not a job i would like while wearing shorts and flip-flops!
Overall, a lovely place but depressing to see the poverty.
Hope the interviews go well.
