Kaduna is an amazing city. Typical northern Nigerian laisser faire scene, good food, very drivable, low traffic and pretty much safe. In the major city centres, the city is very safe and very walkable. You will hear a lot of news about dangerous events happening at the fringes of the state but then, that is like judging a city like new york-based on the crime stats alone and not the actual experience. Colab is the main co-working space here in Barnawa, Kaduna south. Its cheap to rent out a place as you can get a flat in a nice area for 1000 USD for the whole year. Hotels are well nice too at reasonable prices.
